ROLLER CHAIN
Roller chain or bush roller chain is the type of chain drive most commonly used for transmission of mechanical power on many kinds of domestic, industrial and agricultural machinery, including conveyors, wire- and tube-drawing machines, printing presses, cars, motorcycles, and bicycles. It consists of a series of short cylindrical rollers held together by side links. It is driven by a toothed wheel called a sprocket. It is a simple, reliable, and efficient means of power transmission.
CONSTRUCTION OF THE CHAIN
Two different sizes of roller chain, showing construction.
There are 2 types of links alternating in the bush roller chain. The first type is inner links, having 2 inner plates held together by 2 sleeves or bushings CHINAMFG which rotate 2 rollers. Inner links alternate with the second type, the outer links, consisting of 2 outer plates held together by pins passing through the bushings of the inner links. The “bushingless” roller chain is similar in operation though not in construction; instead of separate bushings or sleeves holding the inner plates together, the plate has a tube stamped into it protruding from the hole which serves the same purpose. This has the advantage of removing 1 step in assembly of the chain.
The roller chain design reduces friction compared to simpler designs, resulting in higher efficiency and less wear. The original power transmission chain varieties lacked rollers and bushings, with both the inner and outer plates held by pins which directly contacted the sprocket teeth; however this configuration exhibited extremely rapid wear of both the sprocket teeth, and the plates where they pivoted on the pins. This problem was partially solved by the development of bushed chains, with the pins holding the outer plates passing through bushings or sleeves connecting the inner plates. This distributed the wear over a greater area; however the teeth of the sprockets still wore more rapidly than is desirable, from the sliding friction against the bushings. The addition of rollers surrounding the bushing sleeves of the chain and provided rolling contact with the teeth of the sprockets resulting in excellent resistance to wear of both sprockets and chain as well. There is even very low friction, as long as the chain is sufficiently lubricated. Continuous, clean, lubrication of roller chains is of primary importance for efficient operation as well as correct tensioning.
LUBRICATION
Many driving chains (for example, in factory equipment, or driving a camshaft inside an internal combustion engine) operate in clean environments, and thus the wearing surfaces (that is, the pins and bushings) are safe from precipitation and airborne grit, many even in a sealed environment such as an oil bath. Some roller chains are designed to have o-rings built into the space between the outside link plate and the inside roller link plates. Chain manufacturers began to include this feature in 1971 after the application was invented by Joseph Montano while working for Whitney Chain of Hartford, Connecticut. O-rings were included as a way to improve lubrication to the links of power transmission chains, a service that is vitally important to extending their working life. These rubber fixtures form a barrier that holds factory applied lubricating grease inside the pin and bushing wear areas. Further, the rubber o-rings prevent dirt and other contaminants from entering inside the chain linkages, where such particles would otherwise cause significant wear.[citation needed]
There are also many chains that have to operate in dirty conditions, and for size or operational reasons cannot be sealed. Examples include chains on farm equipment, bicycles, and chain saws. These chains will necessarily have relatively high rates of wear, particularly when the operators are prepared to accept more friction, less efficiency, more noise and more frequent replacement as they neglect lubrication and adjustment.
Many oil-based lubricants attract dirt and other particles, eventually forming an CHINAMFG paste that will compound wear on chains. This problem can be circumvented by use of a “dry” PTFE spray, which forms a solid film after application and repels both particles and moisture.
VARIANTS DESIGN
Layout of a roller chain: 1. Outer plate, 2. Inner plate, 3. Pin, 4. Bushing, 5. Roller
If the chain is not being used for a high wear application (for instance if it is just transmitting motion from a hand-operated lever to a control shaft on a machine, or a sliding door on an oven), then 1 of the simpler types of chain may still be used. Conversely, where extra strength but the smooth drive of a smaller pitch is required, the chain may be “siamesed”; instead of just 2 rows of plates on the outer sides of the chain, there may be 3 (“duplex”), 4 (“triplex”), or more rows of plates running parallel, with bushings and rollers between each adjacent pair, and the same number of rows of teeth running in parallel on the sprockets to match. Timing chains on automotive engines, for example, typically have multiple rows of plates called strands.
Roller chain is made in several sizes, the most common American National Standards Institute (ANSI) standards being 40, 50, 60, and 80. The first digit(s) indicate the pitch of the chain in eighths of an inch, with the last digit being 0 for standard chain, 1 for lightweight chain, and 5 for bushed chain with no rollers. Thus, a chain with half-inch pitch would be a #40 while a #160 sprocket would have teeth spaced 2 inches apart, etc. Metric pitches are expressed in sixteenths of an inch; thus a metric #8 chain (08B-1) would be equivalent to an ANSI #40. Most roller chain is made from plain carbon or alloy steel, but stainless steel is used in food processing machinery or other places where lubrication is a problem, and nylon or brass are occasionally seen for the same reason.
Roller chain is ordinarily hooked up using a master link (also known as a connecting link), which typically has 1 pin held by a horseshoe clip rather than friction fit, allowing it to be inserted or removed with simple tools. Chain with a removable link or pin is also known as cottered chain, which allows the length of the chain to be adjusted. Half links (also known as offsets) are available and are used to increase the length of the chain by a single roller. Riveted roller chain has the master link (also known as a connecting link) “riveted” or mashed on the ends. These pins are made to be durable and are not removable.
USE

Roller chains are used in low- to mid-speed drives at around 600 to 800 feet per minute; however, at higher speeds, around 2,000 to 3,000 feet per minute, V-belts are normally used due to wear and noise issues.
A bicycle chain is a form of roller chain. Bicycle chains may have a master link, or may require a chain tool for removal and installation. A similar but larger and thus stronger chain is used on most motorcycles although it is sometimes replaced by either a toothed belt or a shaft drive, which offer lower noise level and fewer maintenance requirements.
The great majority of automobile engines use roller chains to drive the camshaft(s). Very high performance engines often use gear drive, and starting in the early 1960s toothed belts were used by some manufacturers.
Chains are also used in forklifts using hydraulic rams as a pulley to raise and lower the carriage; however, these chains are not considered roller chains, but are classified as lift or leaf chains.
Chainsaw cutting chains superficially resemble roller chains but are more closely related to leaf chains. They are driven by projecting drive links which also serve to locate the chain CHINAMFG the bar.

A perhaps unusual use of a pair of motorcycle chains is in the Harrier Jump Jet, where a chain drive from an air motor is used to rotate the movable engine nozzles, allowing them to be pointed downwards for hovering flight, or to the rear for normal CHINAMFG flight, a system known as Thrust vectoring.
WEAR
The effect of wear on a roller chain is to increase the pitch (spacing of the links), causing the chain to grow longer. Note that this is due to wear at the pivoting pins and bushes, not from actual stretching of the metal (as does happen to some flexible steel components such as the hand-brake cable of a motor vehicle).
With modern chains it is unusual for a chain (other than that of a bicycle) to wear until it breaks, since a worn chain leads to the rapid onset of wear on the teeth of the sprockets, with ultimate failure being the loss of all the teeth on the sprocket. The sprockets (in particular the smaller of the two) suffer a grinding motion that puts a characteristic hook shape into the driven face of the teeth. (This effect is made worse by a chain improperly tensioned, but is unavoidable no matter what care is taken). The worn teeth (and chain) no longer provides smooth transmission of power and this may become evident from the noise, the vibration or (in car engines using a timing chain) the variation in ignition timing seen with a timing light. Both sprockets and chain should be replaced in these cases, since a new chain on worn sprockets will not last long. However, in less severe cases it may be possible to save the larger of the 2 sprockets, since it is always the smaller 1 that suffers the most wear. Only in very light-weight applications such as a bicycle, or in extreme cases of improper tension, will the chain normally jump off the sprockets.
The lengthening due to wear of a chain is calculated by the following formula:
M = the length of a number of links measured
S = the number of links measured
P = Pitch
In industry, it is usual to monitor the movement of the chain tensioner (whether manual or automatic) or the exact length of a drive chain (one rule of thumb is to replace a roller chain which has elongated 3% on an adjustable drive or 1.5% on a fixed-center drive). A simpler method, particularly suitable for the cycle or motorcycle user, is to attempt to pull the chain away from the larger of the 2 sprockets, whilst ensuring the chain is taut. Any significant movement (e.g. making it possible to see through a gap) probably indicates a chain worn up to and beyond the limit. Sprocket damage will result if the problem is ignored. Sprocket wear cancels this effect, and may mask chain wear.
CHAIN STRENGTH
The most common measure of roller chain’s strength is tensile strength. Tensile strength represents how much load a chain can withstand under a one-time load before breaking. Just as important as tensile strength is a chain’s fatigue strength. The critical factors in a chain’s fatigue strength is the quality of steel used to manufacture the chain, the heat treatment of the chain components, the quality of the pitch hole fabrication of the linkplates, and the type of shot plus the intensity of shot peen coverage on the linkplates. Other factors can include the thickness of the linkplates and the design (contour) of the linkplates. The rule of thumb for roller chain operating on a continuous drive is for the chain load to not exceed a mere 1/6 or 1/9 of the chain’s tensile strength, depending on the type of master links used (press-fit vs. slip-fit)[citation needed]. Roller chains operating on a continuous drive beyond these thresholds can and typically do fail prematurely via linkplate fatigue failure.
The standard minimum ultimate strength of the ANSI 29.1 steel chain is 12,500 x (pitch, in inches)2. X-ring and O-Ring chains greatly decrease wear by means of internal lubricants, increasing chain life. The internal lubrication is inserted by means of a vacuum when riveting the chain together.
CHAIN STHangZhouRDS
Standards organizations (such as ANSI and ISO) maintain standards for design, dimensions, and interchangeability of transmission chains. For example, the following Table shows data from ANSI standard B29.1-2011 (Precision Power Transmission Roller Chains, Attachments, and Sprockets) developed by the American Society of Mechanical Engineers (ASME). See the references[8][9][10] for additional information.

For mnemonic purposes, below is another presentation of key dimensions from the same standard, expressed in fractions of an inch (which was part of the thinking behind the choice of preferred numbers in the ANSI standard):

| 3⁄4 | 6⁄8 | 60 | 1⁄2 |
| 1 | 8⁄8 | 80 | 5⁄8 |
Notes:
1. The pitch is the distance between roller centers. The width is the distance between the link plates (i.e. slightly more than the roller width to allow for clearance).
2. The right-hand digit of the standard denotes 0 = normal chain, 1 = lightweight chain, 5 = rollerless bushing chain.
3. The left-hand digit denotes the number of eighths of an inch that make up the pitch.
4. An “H” following the standard number denotes heavyweight chain. A hyphenated number following the standard number denotes double-strand (2), triple-strand (3), and so on. Thus 60H-3 denotes number 60 heavyweight triple-strand chain.
A typical bicycle chain (for derailleur gears) uses narrow 1⁄2-inch-pitch chain. The width of the chain is variable, and does not affect the load capacity. The more sprockets at the rear wheel (historically 3-6, nowadays 7-12 sprockets), the narrower the chain. Chains are sold according to the number of speeds they are designed to work with, for example, “10 speed chain”. Hub gear or single speed bicycles use 1/2″ x 1/8″ chains, where 1/8″ refers to the maximum thickness of a sprocket that can be used with the chain.
Typically chains with parallel shaped links have an even number of links, with each narrow link followed by a broad one. Chains built up with a uniform type of link, narrow at 1 and broad at the other end, can be made with an odd number of links, which can be an advantage to adapt to a special chainwheel-distance; on the other side such a chain tends to be not so strong.
Roller chains made using ISO standard are sometimes called as isochains.

What are the advantages of using a silent transmission chain?
A silent transmission chain, also known as a silent chain or an inverted-tooth chain, offers several advantages in various applications. Here’s a detailed explanation:
1. Noise Reduction: One of the primary advantages of a silent transmission chain is its ability to minimize noise during operation. The unique design of the chain features inverted teeth that engage with matching sprockets without making direct contact. This design significantly reduces the noise generated by the chain’s movement, resulting in a quieter operation compared to traditional roller chains.
2. Smooth and Vibration-Free Operation: Silent transmission chains provide a smooth and vibration-free power transmission. The absence of metal-to-metal contact between the chain and sprockets reduces friction and vibration, resulting in smoother operation. This characteristic is particularly beneficial in applications where noise and vibrations need to be minimized, such as in precision machinery, office equipment, or medical devices.
3. High Efficiency: Silent transmission chains offer high power transmission efficiency. The precision-engineered tooth profile ensures optimal contact with the sprockets, resulting in efficient energy transfer. The reduced friction and vibration also contribute to improved efficiency by minimizing energy losses during power transmission.
4. Increased Service Life: Silent chains are designed for durability and longevity. The use of high-quality materials, precise manufacturing processes, and robust construction enhance their resistance to wear, elongation, and fatigue. Silent chains can withstand high loads and exhibit excellent resistance to corrosion and lubrication degradation, resulting in extended service life and reduced maintenance requirements.
5. Wide Range of Applications: Silent transmission chains find applications in various industries and systems. They are commonly used in industrial machinery, printing presses, packaging equipment, textile machines, automotive timing systems, and other applications that require low noise, precise power transmission, and long service life.
6. Design Flexibility: Silent chains offer design flexibility due to their ability to operate in a compact space. Their compact design allows for more flexibility in equipment layout and design, making them suitable for applications with space constraints.
7. Reliability and Safety: Silent transmission chains are engineered for reliability and safety. Their robust construction and ability to handle high loads ensure secure power transmission, minimizing the risk of chain failure or system breakdown. Additionally, their low-noise operation and reduced vibration contribute to a safer working environment.
When considering the use of a silent transmission chain, it is important to evaluate the specific requirements of the application, including load capacity, speed, space limitations, and noise considerations. Consulting with chain manufacturers or industry experts can provide valuable insights and assistance in selecting the appropriate silent chain for optimal performance and efficiency.

It’s important to select the appropriate type and size of transmission chain based on the specific requirements of the power transmission system. Regular maintenance and lubrication are also essential to ensure optimal performance and longevity of the transmission chain.
Are there any industry standards or certifications for transmission chains?
Yes, there are industry standards and certifications that govern the manufacturing, quality, and performance of transmission chains. Here’s a detailed explanation:
1. ANSI/ASME Standards: The American National Standards Institute (ANSI) and the American Society of Mechanical Engineers (ASME) have developed standards for transmission chains, such as ANSI/ASME B29.1 for roller chains and ANSI/ASME B29.3 for pintle chains. These standards define the dimensions, materials, tolerances, and performance requirements for various types of transmission chains.
2. ISO Standards: The International Organization for Standardization (ISO) has also established standards for transmission chains, including ISO 606 for short-pitch precision roller chains and ISO 1275 for short-pitch conveyor chains. These standards ensure global consistency and compatibility in terms of chain dimensions and performance.
3. DIN Standards: In Germany, the Deutsches Institut für Normung (DIN) has developed standards for transmission chains, such as DIN 8187 for roller chains and DIN 8181 for bush chains. These standards are widely used in Europe and define the specifications and requirements for chain design and performance.
4. Certifications: In addition to standards, there are certifications that validate the quality and performance of transmission chains. One notable certification is the ISO 9001:2015, which demonstrates that the manufacturer has implemented a quality management system and meets the specified criteria for consistent product quality.
It is important to note that adherence to these standards and certifications is voluntary but highly recommended. Choosing transmission chains that comply with recognized standards and certifications ensures that they have been manufactured and tested to meet specific criteria for performance, reliability, and durability.
When selecting transmission chains, it is advisable to look for products from reputable manufacturers who prioritize quality and compliance with industry standards. This helps to ensure that the chains you choose will meet the necessary requirements for your application and deliver reliable performance over time.

ROLLER CHAIN
Roller chain or bush roller chain is the type of chain drive most commonly used for transmission of mechanical power on many kinds of domestic, industrial and agricultural machinery, including conveyors, wire- and tube-drawing machines, printing presses, cars, motorcycles, and bicycles. It consists of a series of short cylindrical rollers held together by side links. It is driven by a toothed wheel called a sprocket. It is a simple, reliable, and efficient means of power transmission.
CONSTRUCTION OF THE CHAIN
Two different sizes of roller chain, showing construction.
There are 2 types of links alternating in the bush roller chain. The first type is inner links, having 2 inner plates held together by 2 sleeves or bushings CZPT which rotate 2 rollers. Inner links alternate with the second type, the outer links, consisting of 2 outer plates held together by pins passing through the bushings of the inner links. The “bushingless” roller chain is similar in operation though not in construction; instead of separate bushings or sleeves holding the inner plates together, the plate has a tube stamped into it protruding from the hole which serves the same purpose.

This problem was partially solved by the development of bushed chains, with the pins holding the outer plates passing through bushings or sleeves connecting the inner plates. This distributed the wear over a greater area; however the teeth of the sprockets still wore more rapidly than is desirable, from the sliding friction against the bushings. The addition of rollers surrounding the bushing sleeves of the chain and provided rolling contact with the teeth of the sprockets resulting in excellent resistance to wear of both sprockets and chain as well. There is even very low friction, as long as the chain is sufficiently lubricated. Continuous, clean, lubrication of roller chains is of primary importance for efficient operation as well as correct tensioning.

Roller chain is made in several sizes, the most common American National Standards Institute (ANSI) standards being 40, 50, 60, and 80. The first digit(s) indicate the pitch of the chain in eighths of an inch, with the last digit being 0 for standard chain, 1 for lightweight chain, and 5 for bushed chain with no rollers. Thus, a chain with half-inch pitch would be a #40 while a #160 sprocket would have teeth spaced 2 inches apart, etc. Metric pitches are expressed in sixteenths of an inch; thus a metric #8 chain (08B-1) would be equivalent to an ANSI #40.

Half links (also known as offsets) are available and are used to increase the length of the chain by a single roller. Riveted roller chain has the master link (also known as a connecting link) “riveted” or mashed on the ends. These pins are made to be durable and are not removable.
USE

Roller chains are used in low- to mid-speed drives at around 600 to 800 feet per minute; however, at higher speeds, around 2,000 to 3,000 feet per minute, V-belts are normally used due to wear and noise issues.
A bicycle chain is a form of roller chain. Bicycle chains may have a master link, or may require a chain tool for removal and installation. A similar but larger and thus stronger chain is used on most motorcycles although it is sometimes replaced by either a toothed belt or a shaft drive, which offer lower noise level and fewer maintenance requirements.
The great majority of automobile engines use roller chains to drive the camshaft(s). Very high performance engines often use gear drive, and starting in the early 1960s toothed belts were used by some manufacturers.
Chains are also used in forklifts using hydraulic rams as a pulley to raise and lower the carriage; however, these chains are not considered roller chains, but are classified as lift or leaf chains.
Chainsaw cutting chains superficially resemble roller chains but are more closely related to leaf chains. They are driven by projecting drive links which also serve to locate the chain CZPT the bar.

A perhaps unusual use of a pair of motorcycle chains is in the Harrier Jump Jet, where a chain drive from an air motor is used to rotate the movable engine nozzles, allowing them to be pointed downwards for hovering flight, or to the rear for normal CZPT flight, a system known as Thrust vectoring.
WEAR
The effect of wear on a roller chain is to increase the pitch (spacing of the links), causing the chain to grow longer. Note that this is due to wear at the pivoting pins and bushes, not from actual stretching of the metal (as does happen to some flexible steel components such as the hand-brake cable of a motor vehicle).
With modern chains it is unusual for a chain (other than that of a bicycle) to wear until it breaks, since a worn chain leads to the rapid onset of wear on the teeth of the sprockets, with ultimate failure being the loss of all the teeth on the sprocket. The sprockets (in particular the smaller of the two) suffer a grinding motion that puts a characteristic hook shape into the driven face of the teeth. (This effect is made worse by a chain improperly tensioned, but is unavoidable no matter what care is taken). The worn teeth (and chain) no longer provides smooth transmission of power and this may become evident from the noise, the vibration or (in car engines using a timing chain) the variation in ignition timing seen with a timing light. Both sprockets and chain should be replaced in these cases, since a new chain on worn sprockets will not last long. However, in less severe cases it may be possible to save the larger of the 2 sprockets, since it is always the smaller 1 that suffers the most wear. Only in very light-weight applications such as a bicycle, or in extreme cases of improper tension, will the chain normally jump off the sprockets.
The lengthening due to wear of a chain is calculated by the following formula:
M = the length of a number of links measured
S = the number of links measured
P = Pitch
In industry, it is usual to monitor the movement of the chain tensioner (whether manual or automatic) or the exact length of a drive chain (one rule of thumb is to replace a roller chain which has elongated 3% on an adjustable drive or 1.5% on a fixed-center drive). A simpler method, particularly suitable for the cycle or motorcycle user, is to attempt to pull the chain away from the larger of the 2 sprockets, whilst ensuring the chain is taut. Any significant movement (e.g. making it possible to see through a gap) probably indicates a chain worn up to and beyond the limit. Sprocket damage will result if the problem is ignored. Sprocket wear cancels this effect, and may mask chain wear.
CHAIN STRENGTH
The most common measure of roller chain’s strength is tensile strength. Tensile strength represents how much load a chain can withstand under a one-time load before breaking. Just as important as tensile strength is a chain’s fatigue strength. The critical factors in a chain’s fatigue strength is the quality of steel used to manufacture the chain, the heat treatment of the chain components, the quality of the pitch hole fabrication of the linkplates, and the type of shot plus the intensity of shot peen coverage on the linkplates. Other factors can include the thickness of the linkplates and the design (contour) of the linkplates. The rule of thumb for roller chain operating on a continuous drive is for the chain load to not exceed a mere 1/6 or 1/9 of the chain’s tensile strength, depending on the type of master links used (press-fit vs. slip-fit)[citation needed]. Roller chains operating on a continuous drive beyond these thresholds can and typically do fail prematurely via linkplate fatigue failure.
The standard minimum ultimate strength of the ANSI 29.1 steel chain is 12,500 x (pitch, in inches)2. X-ring and O-Ring chains greatly decrease wear by means of internal lubricants, increasing chain life. The internal lubrication is inserted by means of a vacuum when riveting the chain together.

Standards organizations (such as ANSI and ISO) maintain standards for design, dimensions, and interchangeability of transmission chains. For example, the following Table shows data from ANSI standard B29.1-2011 (Precision Power Transmission Roller Chains, Attachments, and Sprockets) developed by the American Society of Mechanical Engineers (ASME). See the references[8][9][10] for additional information.

For mnemonic purposes, below is another presentation of key dimensions from the same standard, expressed in fractions of an inch (which was part of the thinking behind the choice of preferred numbers in the ANSI standard):

| 3⁄4 | 6⁄8 | 60 | 1⁄2 |
| 1 | 8⁄8 | 80 | 5⁄8 |
Notes:
1. The pitch is the distance between roller centers. The width is the distance between the link plates (i.e. slightly more than the roller width to allow for clearance).
2. The right-hand digit of the standard denotes 0 = normal chain, 1 = lightweight chain, 5 = rollerless bushing chain.
3. The left-hand digit denotes the number of eighths of an inch that make up the pitch.
4. An “H” following the standard number denotes heavyweight chain. A hyphenated number following the standard number denotes double-strand (2), triple-strand (3), and so on. Thus 60H-3 denotes number 60 heavyweight triple-strand chain.
A typical bicycle chain (for derailleur gears) uses narrow 1⁄2-inch-pitch chain. The width of the chain is variable, and does not affect the load capacity. The more sprockets at the rear wheel (historically 3-6, nowadays 7-12 sprockets), the narrower the chain. Chains are sold according to the number of speeds they are designed to work with, for example, “10 speed chain”. Hub gear or single speed bicycles use 1/2″ x 1/8″ chains, where 1/8″ refers to the maximum thickness of a sprocket that can be used with the chain.
Typically chains with parallel shaped links have an even number of links, with each narrow link followed by a broad one. Chains built up with a uniform type of link, narrow at 1 and broad at the other end, can be made with an odd number of links, which can be an advantage to adapt to a special chainwheel-distance; on the other side such a chain tends to be not so strong.
Roller chains made using ISO standard are sometimes called as isochains.

What are the benefits of using a maintenance-free transmission chain?
Using a maintenance-free transmission chain offers several advantages in terms of convenience, cost savings, and overall performance. Here’s a detailed explanation:
1. Reduced Maintenance Requirements: Maintenance-free transmission chains are designed to operate without the need for regular lubrication or additional maintenance tasks. This eliminates the time and effort typically associated with lubrication and inspection schedules, reducing overall maintenance requirements and associated costs.
2. Increased Operational Efficiency: Maintenance-free chains often incorporate specialized self-lubricating materials or coatings that provide excellent lubrication properties over an extended period. This helps to reduce friction, wear, and power losses, resulting in improved operational efficiency. The reduced friction also contributes to lower energy consumption and increased power transmission efficiency.
3. Extended Chain Life: Maintenance-free transmission chains are engineered to have a longer service life compared to traditional lubricated chains. The use of self-lubricating materials or coatings helps to minimize wear, corrosion, and elongation, ensuring the chain remains in optimal condition for an extended period. This leads to reduced downtime, fewer chain replacements, and lower replacement costs.
4. Clean and Environmentally Friendly: Maintenance-free chains do not require external lubrication, which means there is no need for oil or grease application. This results in a cleaner and more environmentally friendly working environment, as there is no risk of oil contamination or leakage. Additionally, maintenance-free chains often generate less noise due to reduced friction, contributing to a quieter working environment.
5. Application Versatility: Maintenance-free transmission chains are available in various types and sizes, making them suitable for a wide range of applications. They can be used in industries such as packaging, food processing, automotive, material handling, and many others where reliability, cleanliness, and reduced maintenance are essential.
It’s important to note that while maintenance-free transmission chains offer numerous benefits, they may not be suitable for all applications. Factors such as load capacity, operating conditions, and environmental factors should be considered when determining the appropriate chain type. Consulting with chain manufacturers or industry experts will ensure the selection of a maintenance-free transmission chain that best meets the specific application requirements.
How does the wear resistance of a transmission chain affect its longevity?
Wear resistance is a critical factor that affects the longevity of a transmission chain. Here’s a detailed answer to the question:
1. Extended Lifespan: A transmission chain with high wear resistance is designed to withstand the effects of friction and abrasion, leading to an extended lifespan. It can resist wear caused by contact with sprockets, other chains, or external contaminants, resulting in reduced chain elongation and degradation over time.
2. Reduced Maintenance Requirements: Chains with excellent wear resistance require less frequent maintenance and replacement. They can operate reliably and efficiently for longer periods without significant degradation, reducing downtime and maintenance costs.
3. Improved Performance: A transmission chain with good wear resistance maintains its performance characteristics over time. It can effectively transmit power, maintain accurate speed ratios, and operate smoothly without excessive noise or vibration. This results in improved system performance and overall efficiency.
4. Resistance to Environmental Factors: Chains operating in harsh environments or exposed to contaminants, moisture, or chemicals are more susceptible to wear. A transmission chain with high wear resistance can withstand these environmental factors, ensuring reliable operation and minimizing the negative impact of wear-related issues.
5. Cost Savings: Using a transmission chain with excellent wear resistance can lead to cost savings in the long run. The reduced need for frequent chain replacements, repairs, and maintenance can result in lower operating costs and increased productivity.
It’s important to consider the specific application requirements and operating conditions when selecting a transmission chain. Factors such as load capacity, speed, operating environment, and compatibility with other system components should be evaluated to choose a chain with optimal wear resistance for maximizing longevity and performance.
What are the common industries or applications that use transmission chains?
Transmission chains are widely used in various industries and applications where the efficient transfer of power and motion is required. Here are some common industries and applications that rely on transmission chains:
- Automotive: Transmission chains are used in automobile engines and drivetrains to transfer power from the engine to the wheels.
- Agriculture: Transmission chains are utilized in agricultural machinery such as tractors, combines, and harvesters for power transmission in various applications like conveyor systems and agricultural equipment.
- Industrial Manufacturing: Transmission chains are found in a wide range of industrial machinery, including conveyors, material handling systems, packaging equipment, printing presses, and machine tools.
- Mining and Construction: Transmission chains are used in heavy machinery, such as excavators, bulldozers, and mining equipment, to transmit power for digging, lifting, and other operations.
- Food and Beverage: Transmission chains are employed in food processing equipment, bottling plants, and conveyor systems to move products along production lines.
- Textile: Transmission chains are utilized in textile manufacturing machinery, such as looms and spinning machines, for power transmission during the weaving and spinning processes.
- Energy and Utilities: Transmission chains are used in power generation plants, wind turbines, and other renewable energy systems for transmitting power from the source to the electrical grid.

ROLLER CHAIN
Roller chain or bush roller chain is the type of chain drive most commonly used for transmission of mechanical power on many kinds of domestic, industrial and agricultural machinery, including conveyors, wire- and tube-drawing machines, printing presses, cars, motorcycles, and bicycles. It consists of a series of short cylindrical rollers held together by side links. It is driven by a toothed wheel called a sprocket. It is a simple, reliable, and efficient means of power transmission.
CONSTRUCTION OF THE CHAIN
Two different sizes of roller chain, showing construction.
There are 2 types of links alternating in the bush roller chain. The first type is inner links, having 2 inner plates held together by 2 sleeves or bushings CZPT which rotate 2 rollers. Inner links alternate with the second type, the outer links, consisting of 2 outer plates held together by pins passing through the bushings of the inner links. The “bushingless” roller chain is similar in operation though not in construction; instead of separate bushings or sleeves holding the inner plates together, the plate has a tube stamped into it protruding from the hole which serves the same purpose. This has the advantage of removing 1 step in assembly of the chain.
The roller chain design reduces friction compared to simpler designs, resulting in higher efficiency and less wear. The original power transmission chain varieties lacked rollers and bushings, with both the inner and outer plates held by pins which directly contacted the sprocket teeth; however this configuration exhibited extremely rapid wear of both the sprocket teeth, and the plates where they pivoted on the pins. This problem was partially solved by the development of bushed chains, with the pins holding the outer plates passing through bushings or sleeves connecting the inner plates. This distributed the wear over a greater area; however the teeth of the sprockets still wore more rapidly than is desirable, from the sliding friction against the bushings. The addition of rollers surrounding the bushing sleeves of the chain and provided rolling contact with the teeth of the sprockets resulting in excellent resistance to wear of both sprockets and chain as well. There is even very low friction, as long as the chain is sufficiently lubricated. Continuous, clean, lubrication of roller chains is of primary importance for efficient operation as well as correct tensioning.
LUBRICATION
Many driving chains (for example, in factory equipment, or driving a camshaft inside an internal combustion engine) operate in clean environments, and thus the wearing surfaces (that is, the pins and bushings) are safe from precipitation and airborne grit, many even in a sealed environment such as an oil bath. Some roller chains are designed to have o-rings built into the space between the outside link plate and the inside roller link plates. Chain manufacturers began to include this feature in 1971 after the application was invented by Joseph Montano while working for Whitney Chain of Hartford, Connecticut. O-rings were included as a way to improve lubrication to the links of power transmission chains, a service that is vitally important to extending their working life. These rubber fixtures form a barrier that holds factory applied lubricating grease inside the pin and bushing wear areas. Further, the rubber o-rings prevent dirt and other contaminants from entering inside the chain linkages, where such particles would otherwise cause significant wear.[citation needed]
There are also many chains that have to operate in dirty conditions, and for size or operational reasons cannot be sealed. Examples include chains on farm equipment, bicycles, and chain saws. These chains will necessarily have relatively high rates of wear, particularly when the operators are prepared to accept more friction, less efficiency, more noise and more frequent replacement as they neglect lubrication and adjustment.
Many oil-based lubricants attract dirt and other particles, eventually forming an CZPT paste that will compound wear on chains. This problem can be circumvented by use of a “dry” PTFE spray, which forms a solid film after application and repels both particles and moisture.
VARIANTS DESIGN
Layout of a roller chain: 1. Outer plate, 2. Inner plate, 3. Pin, 4. Bushing, 5. Roller
If the chain is not being used for a high wear application (for instance if it is just transmitting motion from a hand-operated lever to a control shaft on a machine, or a sliding door on an oven), then 1 of the simpler types of chain may still be used. Conversely, where extra strength but the smooth drive of a smaller pitch is required, the chain may be “siamesed”; instead of just 2 rows of plates on the outer sides of the chain, there may be 3 (“duplex”), 4 (“triplex”), or more rows of plates running parallel, with bushings and rollers between each adjacent pair, and the same number of rows of teeth running in parallel on the sprockets to match. Timing chains on automotive engines, for example, typically have multiple rows of plates called strands.
Roller chain is made in several sizes, the most common American National Standards Institute (ANSI) standards being 40, 50, 60, and 80. The first digit(s) indicate the pitch of the chain in eighths of an inch, with the last digit being 0 for standard chain, 1 for lightweight chain, and 5 for bushed chain with no rollers. Thus, a chain with half-inch pitch would be a #40 while a #160 sprocket would have teeth spaced 2 inches apart, etc. Metric pitches are expressed in sixteenths of an inch; thus a metric #8 chain (08B-1) would be equivalent to an ANSI #40. Most roller chain is made from plain carbon or alloy steel, but stainless steel is used in food processing machinery or other places where lubrication is a problem, and nylon or brass are occasionally seen for the same reason.
Roller chain is ordinarily hooked up using a master link (also known as a connecting link), which typically has 1 pin held by a horseshoe clip rather than friction fit, allowing it to be inserted or removed with simple tools. Chain with a removable link or pin is also known as cottered chain, which allows the length of the chain to be adjusted. Half links (also known as offsets) are available and are used to increase the length of the chain by a single roller. Riveted roller chain has the master link (also known as a connecting link) “riveted” or mashed on the ends. These pins are made to be durable and are not removable.

For mnemonic purposes, below is another presentation of key dimensions from the same standard, expressed in fractions of an inch (which was part of the thinking behind the choice of preferred numbers in the ANSI standard):

| 5⁄8 | 5⁄8 | 50 | 3⁄8 |
| 3⁄4 | 6⁄8 | 60 | 1⁄2 |
| 1 | 8⁄8 | 80 | 5⁄8 |
Notes:
1. The pitch is the distance between roller centers. The width is the distance between the link plates (i.e. slightly more than the roller width to allow for clearance).
2. The right-hand digit of the standard denotes 0 = normal chain, 1 = lightweight chain, 5 = rollerless bushing chain.
3. The left-hand digit denotes the number of eighths of an inch that make up the pitch.
4. An “H” following the standard number denotes heavyweight chain. A hyphenated number following the standard number denotes double-strand (2), triple-strand (3), and so on. Thus 60H-3 denotes number 60 heavyweight triple-strand chain.
A typical bicycle chain (for derailleur gears) uses narrow 1⁄2-inch-pitch chain. The width of the chain is variable, and does not affect the load capacity. The more sprockets at the rear wheel (historically 3-6, nowadays 7-12 sprockets), the narrower the chain. Chains are sold according to the number of speeds they are designed to work with, for example, “10 speed chain”. Hub gear or single speed bicycles use 1/2″ x 1/8″ chains, where 1/8″ refers to the maximum thickness of a sprocket that can be used with the chain.
Typically chains with parallel shaped links have an even number of links, with each narrow link followed by a broad one. Chains built up with a uniform type of link, narrow at 1 and broad at the other end, can be made with an odd number of links, which can be an advantage to adapt to a special chainwheel-distance; on the other side such a chain tends to be not so strong.
Roller chains made using ISO standard are sometimes called as isochains.

How does the choice of chain lubricant affect the maintenance requirements?
The choice of chain lubricant has a significant impact on the maintenance requirements of a transmission chain. Here’s a detailed answer to the question:
1. Lubrication Interval: Different chain lubricants have varying properties, including their ability to withstand high temperatures, resist contamination, and provide long-lasting lubrication. The right choice of lubricant can extend the lubrication interval, reducing the frequency of lubrication and, consequently, the maintenance requirements.
2. Wear Protection: The primary function of chain lubrication is to reduce friction and wear between the chain components. The selection of a high-quality lubricant with excellent wear protection properties can significantly extend the chain’s lifespan and reduce the need for frequent replacements or repairs.
3. Contamination Resistance: Some chain lubricants are specifically formulated to resist contaminants such as dust, dirt, or water. Using a lubricant with superior contamination resistance can help maintain optimal chain performance and reduce the risk of premature wear or failure due to the presence of contaminants. This, in turn, reduces the maintenance requirements associated with cleaning and removing contaminants from the chain.
4. Corrosion Prevention: In applications where the chain is exposed to corrosive environments, selecting a chain lubricant with corrosion prevention properties is crucial. Such lubricants form a protective film that helps shield the chain from moisture, chemicals, and other corrosive agents. By using a corrosion-resistant lubricant, the maintenance requirements related to combating corrosion are minimized.
5. Temperature Stability: The operating temperature of a transmission chain can significantly impact its performance and maintenance requirements. Choosing a chain lubricant with excellent temperature stability ensures that the lubricant maintains its viscosity and protective properties even under high temperatures. This reduces the need for frequent lubricant replacements due to thermal degradation.
6. Environmental Considerations: Some applications may have specific environmental regulations or requirements. Choosing a chain lubricant that is environmentally friendly, biodegradable, or compliant with certain standards can simplify maintenance procedures and ensure compliance with regulations.
It’s essential to consult the manufacturer’s recommendations and guidelines when selecting the appropriate chain lubricant for a specific application. Consideration should be given to factors such as operating conditions, load, speed, temperature range, and environmental factors to ensure optimal lubrication and minimize maintenance requirements.
Can transmission chains be used in conveyor systems?
Yes, transmission chains can be used in conveyor systems. Here’s a detailed answer to the question:
Conveyor systems are widely used in various industries for efficient material handling and transportation. Transmission chains are one of the key components used to drive and support the movement of conveyor belts or rollers.
Transmission chains offer several advantages in conveyor systems:
1. Power Transmission: Transmission chains are designed to transmit power effectively, allowing them to drive the movement of the conveyor belt or rollers. They can handle high loads and provide reliable power transfer, ensuring smooth and consistent operation of the conveyor system.
2. Versatility: Transmission chains are available in various sizes, types, and configurations, making them suitable for a wide range of conveyor applications. They can be customized to fit different conveyor system designs and requirements, including straight conveyors, curved conveyors, inclined conveyors, and more.
3. Durability: Transmission chains are built to withstand rigorous operating conditions in conveyor systems. They are made from high-quality materials such as steel, which offers excellent strength and durability. This ensures that the chains can withstand heavy loads, frequent starts and stops, and abrasive environments commonly encountered in conveyor applications.
4. Flexibility: Transmission chains allow for flexibility in conveyor system layout and configuration. They can accommodate different conveyor lengths, widths, and angles, enabling the system to adapt to space constraints and specific material handling needs. Additionally, they can be easily modified or extended as the conveyor system requirements evolve.
5. Low Maintenance: Transmission chains require regular maintenance to ensure optimal performance and longevity. However, compared to other types of power transmission systems, such as belts or gears, transmission chains generally have lower maintenance requirements. Proper lubrication, tensioning, and periodic inspections are essential to minimize wear and ensure reliable operation of the conveyor system.
Overall, transmission chains are a reliable and efficient solution for powering conveyor systems. They provide robust power transmission, versatility in system design, durability in demanding environments, flexibility in layout, and relatively low maintenance requirements. When properly selected and maintained, transmission chains can contribute to the smooth and efficient operation of conveyor systems in various industries.
How does the choice of sprockets impact the performance of a transmission chain?
The choice of sprockets has a significant impact on the performance and longevity of a transmission chain. Here’s a detailed explanation:
1. Tooth Profile: The tooth profile of the sprockets should match the design of the transmission chain. Common tooth profiles include standard, modified, and special profiles. Proper matching ensures smooth engagement, reduced noise, and efficient power transmission.
2. Pitch Diameter: The pitch diameter of the sprockets determines the chain’s speed ratio and the rotational speed of the driven component. It should be selected based on the desired speed and torque requirements of the system.
3. Number of Teeth: The number of teeth on the sprockets affects the chain’s engagement and load distribution. Sprockets with a higher number of teeth distribute the load over more contact points, reducing wear and increasing the chain’s capacity to handle higher loads.
4. Material Selection: The material of the sprockets should be compatible with the chain and the operating environment. Common materials include steel, stainless steel, and plastics. Consider factors such as strength, wear resistance, and corrosion resistance when selecting the sprocket material.
5. Sprocket Hardness: The hardness of the sprockets is important to withstand the chain’s contact forces and resist wear. Proper hardness ensures that the sprockets maintain their tooth profile and engage with the chain effectively over an extended period.
6. Sprocket Alignment: Proper alignment of the sprockets is crucial to minimize wear, noise, and premature failure. Misalignment can lead to uneven load distribution, increased stress on the chain, and accelerated wear. Ensure that the sprockets are aligned both axially and radially to maintain optimal performance.
7. Lubrication: Sprockets should be adequately lubricated to reduce friction, wear, and heat generation. Proper lubrication ensures smooth rotation and minimizes the risk of chain failure. Consider using lubricants specifically formulated for sprocket and chain applications.
8. Maintenance: Regular inspection and maintenance of the sprockets are essential to detect any signs of wear, misalignment, or damage. Replace worn or damaged sprockets promptly to prevent chain slippage, excessive wear, and potential system failure.
Choosing the appropriate sprockets that are compatible with the transmission chain and the operating conditions is critical for achieving reliable and efficient performance. Consult the manufacturer’s guidelines and recommendations for selecting the right sprockets based on the specific application requirements.

ROLLER CHAIN
Roller chain or bush roller chain is the type of chain drive most commonly used for transmission of mechanical power on many kinds of domestic, industrial and agricultural machinery, including conveyors, wire- and tube-drawing machines, printing presses, cars, motorcycles, and bicycles. It consists of a series of short cylindrical rollers held together by side links. It is driven by a toothed wheel called a sprocket. It is a simple, reliable, and efficient means of power transmission.
CONSTRUCTION OF THE CHAIN
Two different sizes of roller chain, showing construction.
There are 2 types of links alternating in the bush roller chain. The first type is inner links, having 2 inner plates held together by 2 sleeves or bushings CZPT which rotate 2 rollers. Inner links alternate with the second type, the outer links, consisting of 2 outer plates held together by pins passing through the bushings of the inner links. The “bushingless” roller chain is similar in operation though not in construction; instead of separate bushings or sleeves holding the inner plates together, the plate has a tube stamped into it protruding from the hole which serves the same purpose. This has the advantage of removing 1 step in assembly of the chain.
The roller chain design reduces friction compared to simpler designs, resulting in higher efficiency and less wear. The original power transmission chain varieties lacked rollers and bushings, with both the inner and outer plates held by pins which directly contacted the sprocket teeth; however this configuration exhibited extremely rapid wear of both the sprocket teeth, and the plates where they pivoted on the pins. This problem was partially solved by the development of bushed chains, with the pins holding the outer plates passing through bushings or sleeves connecting the inner plates. This distributed the wear over a greater area; however the teeth of the sprockets still wore more rapidly than is desirable, from the sliding friction against the bushings. The addition of rollers surrounding the bushing sleeves of the chain and provided rolling contact with the teeth of the sprockets resulting in excellent resistance to wear of both sprockets and chain as well. There is even very low friction, as long as the chain is sufficiently lubricated. Continuous, clean, lubrication of roller chains is of primary importance for efficient operation as well as correct tensioning.
LUBRICATION
Many driving chains (for example, in factory equipment, or driving a camshaft inside an internal combustion engine) operate in clean environments, and thus the wearing surfaces (that is, the pins and bushings) are safe from precipitation and airborne grit, many even in a sealed environment such as an oil bath. Some roller chains are designed to have o-rings built into the space between the outside link plate and the inside roller link plates. Chain manufacturers began to include this feature in 1971 after the application was invented by Joseph Montano while working for Whitney Chain of Hartford, Connecticut. O-rings were included as a way to improve lubrication to the links of power transmission chains, a service that is vitally important to extending their working life. These rubber fixtures form a barrier that holds factory applied lubricating grease inside the pin and bushing wear areas. Further, the rubber o-rings prevent dirt and other contaminants from entering inside the chain linkages, where such particles would otherwise cause significant wear.[citation needed]
There are also many chains that have to operate in dirty conditions, and for size or operational reasons cannot be sealed. Examples include chains on farm equipment, bicycles, and chain saws. These chains will necessarily have relatively high rates of wear, particularly when the operators are prepared to accept more friction, less efficiency, more noise and more frequent replacement as they neglect lubrication and adjustment.
Many oil-based lubricants attract dirt and other particles, eventually forming an CZPT paste that will compound wear on chains. This problem can be circumvented by use of a “dry” PTFE spray, which forms a solid film after application and repels both particles and moisture.
VARIANTS DESIGN
Layout of a roller chain: 1. Outer plate, 2. Inner plate, 3. Pin, 4. Bushing, 5. Roller
If the chain is not being used for a high wear application (for instance if it is just transmitting motion from a hand-operated lever to a control shaft on a machine, or a sliding door on an oven), then 1 of the simpler types of chain may still be used. Conversely, where extra strength but the smooth drive of a smaller pitch is required, the chain may be “siamesed”; instead of just 2 rows of plates on the outer sides of the chain, there may be 3 (“duplex”), 4 (“triplex”), or more rows of plates running parallel, with bushings and rollers between each adjacent pair, and the same number of rows of teeth running in parallel on the sprockets to match. Timing chains on automotive engines, for example, typically have multiple rows of plates called strands.
Roller chain is made in several sizes, the most common American National Standards Institute (ANSI) standards being 40, 50, 60, and 80. The first digit(s) indicate the pitch of the chain in eighths of an inch, with the last digit being 0 for standard chain, 1 for lightweight chain, and 5 for bushed chain with no rollers. Thus, a chain with half-inch pitch would be a #40 while a #160 sprocket would have teeth spaced 2 inches apart, etc. Metric pitches are expressed in sixteenths of an inch; thus a metric #8 chain (08B-1) would be equivalent to an ANSI #40. Most roller chain is made from plain carbon or alloy steel, but stainless steel is used in food processing machinery or other places where lubrication is a problem, and nylon or brass are occasionally seen for the same reason.
Roller chain is ordinarily hooked up using a master link (also known as a connecting link), which typically has 1 pin held by a horseshoe clip rather than friction fit, allowing it to be inserted or removed with simple tools. Chain with a removable link or pin is also known as cottered chain, which allows the length of the chain to be adjusted. Half links (also known as offsets) are available and are used to increase the length of the chain by a single roller. Riveted roller chain has the master link (also known as a connecting link) “riveted” or mashed on the ends. These pins are made to be durable and are not removable.
USE
An example of 2 ‘ghost’ sprockets tensioning a triplex roller chain system
Roller chains are used in low- to mid-speed drives at around 600 to 800 feet per minute; however, at higher speeds, around 2,000 to 3,000 feet per minute, V-belts are normally used due to wear and noise issues.
A bicycle chain is a form of roller chain. Bicycle chains may have a master link, or may require a chain tool for removal and installation. A similar but larger and thus stronger chain is used on most motorcycles although it is sometimes replaced by either a toothed belt or a shaft drive, which offer lower noise level and fewer maintenance requirements.
The great majority of automobile engines use roller chains to drive the camshaft(s). Very high performance engines often use gear drive, and starting in the early 1960s toothed belts were used by some manufacturers.
Chains are also used in forklifts using hydraulic rams as a pulley to raise and lower the carriage; however, these chains are not considered roller chains, but are classified as lift or leaf chains.
Chainsaw cutting chains superficially resemble roller chains but are more closely related to leaf chains. They are driven by projecting drive links which also serve to locate the chain CZPT the bar.

A perhaps unusual use of a pair of motorcycle chains is in the Harrier Jump Jet, where a chain drive from an air motor is used to rotate the movable engine nozzles, allowing them to be pointed downwards for hovering flight, or to the rear for normal CZPT flight, a system known as Thrust vectoring.
WEAR
The effect of wear on a roller chain is to increase the pitch (spacing of the links), causing the chain to grow longer. Note that this is due to wear at the pivoting pins and bushes, not from actual stretching of the metal (as does happen to some flexible steel components such as the hand-brake cable of a motor vehicle).
With modern chains it is unusual for a chain (other than that of a bicycle) to wear until it breaks, since a worn chain leads to the rapid onset of wear on the teeth of the sprockets, with ultimate failure being the loss of all the teeth on the sprocket. The sprockets (in particular the smaller of the two) suffer a grinding motion that puts a characteristic hook shape into the driven face of the teeth. (This effect is made worse by a chain improperly tensioned, but is unavoidable no matter what care is taken). The worn teeth (and chain) no longer provides smooth transmission of power and this may become evident from the noise, the vibration or (in car engines using a timing chain) the variation in ignition timing seen with a timing light. Both sprockets and chain should be replaced in these cases, since a new chain on worn sprockets will not last long. However, in less severe cases it may be possible to save the larger of the 2 sprockets, since it is always the smaller 1 that suffers the most wear. Only in very light-weight applications such as a bicycle, or in extreme cases of improper tension, will the chain normally jump off the sprockets.
The lengthening due to wear of a chain is calculated by the following formula:
M = the length of a number of links measured
S = the number of links measured
P = Pitch
In industry, it is usual to monitor the movement of the chain tensioner (whether manual or automatic) or the exact length of a drive chain (one rule of thumb is to replace a roller chain which has elongated 3% on an adjustable drive or 1.5% on a fixed-center drive). A simpler method, particularly suitable for the cycle or motorcycle user, is to attempt to pull the chain away from the larger of the 2 sprockets, whilst ensuring the chain is taut. Any significant movement (e.g. making it possible to see through a gap) probably indicates a chain worn up to and beyond the limit. Sprocket damage will result if the problem is ignored. Sprocket wear cancels this effect, and may mask chain wear.
CHAIN STRENGTH
The most common measure of roller chain’s strength is tensile strength. Tensile strength represents how much load a chain can withstand under a one-time load before breaking. Just as important as tensile strength is a chain’s fatigue strength. The critical factors in a chain’s fatigue strength is the quality of steel used to manufacture the chain, the heat treatment of the chain components, the quality of the pitch hole fabrication of the linkplates, and the type of shot plus the intensity of shot peen coverage on the linkplates. Other factors can include the thickness of the linkplates and the design (contour) of the linkplates. The rule of thumb for roller chain operating on a continuous drive is for the chain load to not exceed a mere 1/6 or 1/9 of the chain’s tensile strength, depending on the type of master links used (press-fit vs. slip-fit)[citation needed]. Roller chains operating on a continuous drive beyond these thresholds can and typically do fail prematurely via linkplate fatigue failure.
The standard minimum ultimate strength of the ANSI 29.1 steel chain is 12,500 x (pitch, in inches)2. X-ring and O-Ring chains greatly decrease wear by means of internal lubricants, increasing chain life. The internal lubrication is inserted by means of a vacuum when riveting the chain together.
CHAIN STHangZhouRDS
Standards organizations (such as ANSI and ISO) maintain standards for design, dimensions, and interchangeability of transmission chains. For example, the following Table shows data from ANSI standard B29.1-2011 (Precision Power Transmission Roller Chains, Attachments, and Sprockets) developed by the American Society of Mechanical Engineers (ASME). See the references[8][9][10] for additional information.

4. Positioning and Orientation: Some applications require precise positioning or orientation of objects or components. Chain attachments, such as indexing pins or brackets, are designed to facilitate accurate positioning or rotation of objects along the chain’s path. These attachments contribute to the reliable and precise operation of the transmission chain.
5. Material Handling: In material handling applications, chain attachments are often used to secure or hold items during transport. Attachments like hooks, clamps, or brackets enable the secure attachment of objects to the chain, preventing slippage or displacement during movement. This ensures safe and efficient material handling operations.
6. Specialized Functions: Chain attachments can provide additional functions based on specific application requirements. For example, attachments such as sensors, RFID tags, or lubrication reservoirs can be integrated into the chain design to enable monitoring, tracking, or lubrication functions. These specialized attachments enhance the overall functionality and performance of the transmission chain.
It’s important to select the appropriate chain attachment based on the specific application needs, load requirements, and desired functionality. Consulting with industry experts or chain manufacturers can help in determining the most suitable attachment options for optimal transmission chain performance.
Can transmission chains be used in power transmission systems?
Yes, transmission chains can be used in power transmission systems. Here’s a detailed answer to the question:
Transmission chains are commonly employed in various power transmission applications where the transfer of mechanical power is required. These chains are designed to transmit rotational motion and power from one shaft to another.
Transmission chains are used in a wide range of power transmission systems, including:
- Industrial Machinery: Transmission chains are used in machinery such as conveyor systems, packaging equipment, printing presses, and machine tools to transfer power and motion between different components.
- Agricultural Equipment: Transmission chains are utilized in farm machinery like tractors, combines, and harvesters to transmit power from the engine to various mechanical components for tasks like cutting, threshing, and planting.
- Automotive: Transmission chains can be found in certain automotive applications, such as motorcycle drive chains or timing chains that synchronize the rotation of the crankshaft and camshaft in internal combustion engines.
- Power Generation: Transmission chains are employed in power generation systems, including wind turbines, hydroelectric turbines, and steam turbines, to transmit rotational motion from the turbine to the generator.
- Construction Equipment: Transmission chains are used in construction equipment like excavators, loaders, and bulldozers to transfer power and motion from the engine to the drivetrain and various hydraulic components.
Transmission chains offer several advantages in power transmission systems:
- High Efficiency: Transmission chains have minimal power losses, allowing for efficient power transfer.
- High Load Capacity: Transmission chains are capable of handling high loads and transmitting substantial amounts of power.
- Flexibility: Transmission chains can be easily customized to fit different applications, with various sizes, lengths, and configurations available.
- Durability: Transmission chains are designed to withstand heavy-duty applications and offer long service life when properly maintained.
- Cost-Effective: Transmission chains are often a cost-effective solution compared to other power transmission options.
It’s important to select the appropriate type and size of transmission chain based on the specific requirements of the power transmission system. Regular maintenance and lubrication are also essential to ensure optimal performance and longevity of the transmission chain.
What are the main differences between standard and heavy-duty transmission chains?
Standard and heavy-duty transmission chains are designed to meet different load and performance requirements. Here are the main differences between these two types:
- Load Capacity: Heavy-duty transmission chains are built to handle higher loads and provide greater strength compared to standard chains. They are designed to withstand heavier and more demanding applications.
- Construction: Heavy-duty transmission chains are typically constructed with thicker plates, larger pins, and stronger components to enhance their durability and load-carrying capacity.
- Size: Heavy-duty transmission chains are often larger in size compared to standard chains to accommodate the increased load requirements.
- Weight: Due to their robust construction, heavy-duty transmission chains tend to be heavier than standard chains.
- Durability: Heavy-duty chains are engineered to have greater wear resistance, fatigue resistance, and overall durability to withstand harsh operating conditions and prolonged usage.
- Applications: Standard transmission chains are suitable for lighter-duty applications where moderate loads are involved, such as light machinery, conveyors, and small equipment. Heavy-duty transmission chains, on the other hand, are designed for heavy machinery, industrial equipment, mining applications, and other demanding environments.
It’s important to consider the specific requirements of your application, including load capacity, operating conditions, and expected lifespan, to determine whether a standard or heavy-duty transmission chain is the right choice.

What is a roller chain?
What is a roller chain? A roller chain is a transmission system that transmits power from one shaft to another. Internal lubricant helps chains last longer and are interchangeable. Chains are usually made of carbon or alloy steel. Stainless steel is sometimes used in food processing machinery or in environments where lubrication is problematic. Brass and nylon are also sometimes used. If you need to slow down the machine, nylon chains can be used.
Roller chains are used to transmit power from one shaft to another
Generally speaking, the life of a roller chain is limited by three main factors: wear, corrosion, and fatigue. These can be minimized by following some simple guidelines. For optimum performance, the roller chain must be lubricated. Proper lubrication reduces friction and extends product life. Remember that corrosion and wind resistance can adversely affect lubrication, so protect the product properly.
A chain is a mechanical device used to transmit power from one shaft to another. The chain consists of a series of steel plates called bushings. Bushings are attached to the roller chain by pins or bushings. The block and bushing are held together by pins or bushings C riveted to the outer link D. The chain is also attached to the sprocket and bucket by pins or hooks. Chain pitch is measured between hinge centers, usually denoted p.
There are three types of chains: single-strand standard series, multi-strand standard series, and silent chain. Single strand chains are the most common type and cover a wide range of drive loads. Multi-strand chains provide greater power capacity without increasing chain pitch or line speed. An inverted tooth chain is a variant of a single-strand chain that eliminates the noise caused by pitch-related friction.
The inner and outer plates of the roller chain drive are made of steel. The rollers are positioned evenly between the chain links and are fastened to the sprockets. In addition, the rollers can rotate freely within the bushing. The chain links are arc-shaped and mesh with the sprocket teeth to transmit power through the chain.
Chain drives are another common way of transmitting mechanical power. These are the simplest forms of power transmission and are used on conveyor belts and other low-speed applications. The chain wraps around the sprocket and passes through the sprocket whose teeth mesh with the links. This mechanism transfers mechanical power from one shaft to another, increasing speed.
They are interchangeable
There are many different types of roller chains, but most are made of steel. Although they have their own advantages and features, they are generally interchangeable. You can buy different kinds of roller chains from domestic and foreign manufacturers, and you can choose the one that best suits your needs. Bearing Services can help you choose the right bearing for your application needs and budget. Here are some important things to consider before buying a roller chain. Here are some tips to make it easier for you to buy the right type of chain.
When choosing the right roller chain, be sure to consult the available size charts. Depends on how much chain you need to move the load you need to move. Remember that roller chains can be manufactured to fit a variety of machines and must meet your specific needs. Also, the chain should be long enough for the machine you are using. Make sure to buy a chain made of high-quality materials.
Double pitch roller chains have a flat top surface and are used in many different conveying applications. Double-pitch load-carrying roller chains, also known as oversized roller double-pitch chains, have rollers that extend beyond the sidebars to carry products. Double pitch drive series roller chains are used in elevators, long conveyor drives, agricultural machinery, and commercial sprinkler systems.
The tensile strength of a roller chain is a key factor to consider before purchasing a chain. The tensile strength of a chain is a function of the maximum force the chain can withstand before breaking. The three different types of tensile strength represent the force a chain can withstand without breaking. Each chain also has different strengths that can determine the type of chain you need.
The outer and inner links of the roller chain are designed for bearings. This allows the chain to be paired or unpaired with its internal links. The outer link has a pin, and the inner and outer pins are press-fit into the connecting plate. These links are usually made of steel and have a tensile strength of about 20 times their weight. The fatigue strength of two-pitch offset links is the same as that of the base chain.
They reduce wear with internal lubricants
In a roller chain, the pins and bushings rotate inside the chain without lubricant on the outside. They are in contact with the teeth of the sprocket and can easily wear out if not lubricated. The plates that connect the links and pivot about the pins can also rub against each other and cause wear. This is where lubricants come in handy. Without lubricant, the bare metal of the plate and bushing would rub against each other.
The lubricant should have the appropriate viscosity to penetrate critical internal surfaces and form an effective oil film. Recommended viscosities are listed in Table 1. Lubricants must be clean and non-corrosive. For roller chains, a good quality non-clean petroleum base oil is sufficient. While defoamers are not required, other additives such as antioxidants and extreme pressure inhibitors may be useful. However, impure oils should be avoided due to the risk of damage.
The shape of the spray head 10 overlaps with a conventional drive chain 12. The drive chain includes a plurality of rollers 24 and roller link plates 26. Each roller includes a roller pin 29 and is connected to a pair of pin link plates 28. Most drive chains have critical wear points on the sides of the roller pins 29. The shape of the spray head 10 prevents overspray onto the central portion of the roller.
In addition to preventing wear, these chains have unique specifications. Manufacturer CZPT requires raw material suppliers to certify that their products meet standards set by the American Society of Mechanical Engineers (ASME). CZPTs do not accept uncertified raw materials. For safety, the machine must be turned off before attempting to measure the chain. After the system is shut down, the measurement process should be completed in accordance with safety procedures.
General spray oil has lubricating properties, but is not as good as other types of chain lubricants. These are typically used for rust protection and include antioxidant chemicals. Generally, they are inexpensive and widely available in retail stores. However, they have the disadvantage of being very penetrating and difficult to apply evenly. Oil cannot stay on the chain as it spins, which can accelerate wear and corrosion.
They can be used to speed up or slow down machines
Typically, roller chains are chains used to move mechanical system components. Unlike belts, roller chains can be used to speed up or slow down a machine. The main difference between belts and roller chains is the lubrication process. Belts use lubrication to help them move at a constant speed, but should not exceed the critical speed of the roller chain. This critical speed is not easy to determine and lubrication is critical to its life.
A roller chain is a chain consisting of a steel bushing that holds the inner plate A and pins C together. Pin C is riveted to outer link D, while roller R surrounds each bushing B. The teeth of the sprocket are supported on the rollers. They spin freely on pins and bushings, reducing friction.
The chains can be single-stranded, double-stranded, or multi-stranded. The rated power capacity of the single strand chain can meet various drive load requirements. Multi-strand chains provide higher power capacity without increasing chain pitch or line speed. The silent chain, also known as the inverted tooth chain, consists of a series of toothed chainplates. The pins of the chain are pressed into the wide ends of the sidebars and outer links.
Although roller chains are a common mechanical component, they can fail under certain conditions. The most common cause of excessive wear is wrong to load sizing. Each manufacturer sets a maximum workload for its product. A chain that is too small for the load carried will not run smoothly and may cause premature failure. Chains can also fail due to rust or improper maintenance.
There are many ways to choose the correct size roller chain. The easiest way to choose the right one is to use a horsepower chart to determine the speed of the motor. RPM will determine the size of the chain and the number of teeth on the drive sprocket. Conveyor chains offer a variety of options to move products horizontally or vertically, even around bend radii.

Installation AND Using
The chain spoket, as a push or deflection for chains, has pockets to maintain the chain links with a D-profile CZPT section with flat facet surfaces parallel to the centre aircraft of the chain back links, and outer surfaces at appropriate angles to the chain website link centre plane. The chain hyperlinks are pressed firmly against the outer surfaces and each and every of the side surfaces by the angled laying surfaces at the base of the pockets, and also the help surfaces of the wheel entire body with each other with the stop sides of the webs shaped by the top and trailing partitions of the pocket.
Observe
When CZPT new chainwheels it is quite essential that a new chain is fitted at the exact same time, and vice versa. Using an previous chain with new sprockets, or a new chain with old sprockets will result in fast dress in.
It is important if you are putting in the chainwheels your self to have the factory support manual distinct to your design. Our chainwheels are made to be a direct CZPT for your OEM chainwheels and as this sort of, the installation should be performed according to your versions support manual.
In the course of use a chain will extend (i.e. the pins will dress in causing extension of the chain). Making use of a chain which has been stretched far more than the above maximum allowance triggers the chain to trip up the tooth of the sprocket. This leads to damage to the suggestions of the chainwheels tooth, as the force transmitted by the chain is transmitted entirely via the leading of the tooth, rather than the whole tooth. This results in extreme putting on of the chainwheel.
FOR CHAIN STHangZhouRDS
Specifications businesses (this kind of as ANSI and ISO) keep expectations for design, dimensions, and interchangeability of transmission chains. For case in point, the following Desk shows information from ANSI normal B29.1-2011 (Precision Electrical power Transmission Roller Chains, Attachments, and Sprockets) developed by the American Culture of Mechanical Engineers (ASME). See the references[8][9][ten] for additional info.

For mnemonic functions, underneath is one more presentation of essential proportions from the same regular, expressed in fractions of an inch (which was component of the thinking guiding the decision of preferred figures in the ANSI standard):
| Pitch (inches) | Pitch expressed in eighths |
ANSI normal chain number |
Width (inches) |
|---|---|---|---|
| one⁄four | two⁄eight | 2five | one⁄8 |
| 3⁄8 | 3⁄eight | 3five | three⁄16 |
| 1⁄2 | 4⁄eight | 41 | one⁄four |

| 5⁄8 | five⁄eight | five | three⁄eight |
| 3⁄four | 6⁄eight | 6 | one⁄two |
| one | 8⁄eight | eight | 5⁄8 |
Notes:
1. The pitch is the distance between roller facilities. The width is the length in between the website link plates (i.e. a bit a lot more than the roller width to let for clearance).
2. The appropriate-hand digit of the common denotes 0 = normal chain, 1 = lightweight chain, 5 = rollerless bushing chain.
3. The remaining-hand digit denotes the number of eighths of an inch that make up the pitch.
four. An “H” pursuing the standard number denotes heavyweight chain. A hyphenated amount subsequent the regular quantity denotes double-strand (2), triple-strand (3), and so on. Hence 60H-3 denotes variety 60 heavyweight triple-strand chain.
A common bicycle chain (for derailleur gears) uses slim 1⁄2-inch-pitch chain. The width of the chain is variable, and does not influence the load ability. The far more sprockets at the rear wheel (historically 3-6, today 7-twelve sprockets), the narrower the chain. Chains are sold in accordance to the amount of speeds they are created to perform with, for case in point, “ten pace chain”. Hub equipment or solitary speed bicycles use 1/2″ x 1/8″ chains, in which 1/8″ refers to the highest thickness of a sprocket that can be employed with the chain.
Typically chains with parallel formed links have an even variety of links, with each slender url adopted by a broad 1.Chains constructed up with a uniform type of link, slim at 1 and broad at the other finish, can be produced with an odd quantity of backlinks, which can be an benefit to adapt to a special chainwheel-distance on the other aspect this kind of a chain tends to be not so sturdy.
Roller chains created making use of ISO normal are sometimes named as isochains.

Installation AND Making use of
The chain spoket, as a generate or deflection for chains, has pockets to maintain the chain backlinks with a D-profile CZPT section with flat aspect surfaces parallel to the centre aircraft of the chain back links, and outer surfaces at appropriate angles to the chain link centre plane. The chain backlinks are pressed firmly in opposition to the outer surfaces and each of the aspect surfaces by the angled laying surfaces at the base of the pockets, and also the assistance surfaces of the wheel entire body collectively with the finish sides of the webs fashioned by the leading and trailing walls of the pocket.
Discover
When CZPT new chainwheels it is extremely critical that a new chain is fitted at the very same time, and vice versa. Making use of an old chain with new sprockets, or a new chain with old sprockets will trigger speedy put on.
It is essential if you are installing the chainwheels by yourself to have the manufacturing facility services manual certain to your model. Our chainwheels are produced to be a direct CZPT for your OEM chainwheels and as this sort of, the set up should be carried out according to your types provider guide.
In the course of use a chain will extend (i.e. the pins will put on leading to extension of the chain). Employing a chain which has been stretched much more than the over maximum allowance causes the chain to experience up the teeth of the sprocket. This brings about injury to the ideas of the chainwheels teeth, as the drive transmitted by the chain is transmitted entirely by means of the prime of the tooth, rather than the entire tooth. This benefits in extreme donning of the chainwheel.

Expectations businesses (these kinds of as ANSI and ISO) maintain specifications for layout, dimensions, and interchangeability of transmission chains. For case in point, the adhering to Table exhibits knowledge from ANSI normal B29.1-2011 (Precision Electrical power Transmission Roller Chains, Attachments, and Sprockets) designed by the American Society of Mechanical Engineers (ASME).

For mnemonic needs, beneath is one more presentation of crucial proportions from the identical standard, expressed in fractions of an inch (which was part of the pondering powering the choice of favored figures in the ANSI regular):
| Pitch (inches) | Pitch expressed in eighths |
ANSI standard chain quantity |
Width (inches) |
|---|---|---|---|
| one⁄four | 2⁄8 | two5 | one⁄eight |
| three⁄eight | 3⁄eight | 35 | 3⁄16 |
| one⁄2 | 4⁄8 | 41 | one⁄4 |

| five⁄8 | five⁄eight | 5 | 3⁄8 |
| 3⁄four | six⁄eight | 6 | one⁄2 |
| 1 | 8⁄8 | eight | 5⁄8 |
Notes:
one. The pitch is the distance between roller facilities. The width is the length in between the url plates (i.e. somewhat a lot more than the roller width to allow for clearance).
two. The correct-hand digit of the normal denotes 0 = standard chain, 1 = lightweight chain, 5 = rollerless bushing chain.
three. The still left-hand digit denotes the number of eighths of an inch that make up the pitch.
4. An “H” subsequent the normal amount denotes heavyweight chain. A hyphenated amount subsequent the regular quantity denotes double-strand (2), triple-strand (3), and so on. Hence 60H-3 denotes variety sixty heavyweight triple-strand chain.
A common bicycle chain (for derailleur gears) uses narrow 1⁄2-inch-pitch chain. The width of the chain is variable, and does not affect the load capability. The more sprockets at the rear wheel (traditionally 3-6, today 7-12 sprockets), the narrower the chain. Chains are offered according to the variety of speeds they are created to work with, for example, “ten velocity chain”. Hub gear or single pace bicycles use 1/2″ x 1/8″ chains, where 1/8″ refers to the greatest thickness of a sprocket that can be utilized with the chain.
Normally chains with parallel formed hyperlinks have an even variety of back links, with each slender hyperlink adopted by a broad 1.Chains developed up with a uniform kind of link, slim at 1 and wide at the other finish, can be manufactured with an odd variety of hyperlinks, which can be an gain to adapt to a special chainwheel-length on the other side such a chain tends to be not so strong.
Roller chains made using ISO regular are sometimes called as isochains.

Drum sprockets: These sprockets are generally wider to enhance the overall area contact amongst the sprocket and chain. This minimizes anxiety on the two sections, generating a a lot more sturdy method for large haul conveyors.
The tooth of a one pitch sprocket mesh with one particular tooth for each sprocket. Double pitch sprockets search like solitary pitch sprockets, but the chain only meshes with the other teeth. This implies that a double-pitch sprocket has the identical amount of enamel as a one-pitch sprocket, but only 50 percent of the tooth are engaged with the chain. The primary big difference is that the double pitch sprockets are lower with a unique pitch circle diameter for optimum engagement. For ep roller chains, the sprockets are the identical if the amount of enamel is 32 or a lot more for solitary and double chains.

Installation AND Employing
The chain spoket, as a generate or deflection for chains, has pockets to hold the chain links with a D-profile CZPT segment with flat facet surfaces parallel to the centre airplane of the chain links, and outer surfaces at proper angles to the chain website link centre airplane. The chain hyperlinks are pressed firmly against the outer surfaces and each and every of the aspect surfaces by the angled laying surfaces at the foundation of the pockets, and also the assist surfaces of the wheel entire body jointly with the end sides of the webs formed by the major and trailing walls of the pocket.

When CZPT new chainwheels it is extremely crucial that a new chain is equipped at the same time, and vice versa. Employing an previous chain with new sprockets, or a new chain with outdated sprockets will cause speedy put on.
It is important if you are setting up the chainwheels by yourself to have the manufacturing unit provider handbook particular to your product. Our chainwheels are manufactured to be a direct CZPT for your OEM chainwheels and as this sort of, the installation must be carried out in accordance to your designs service manual.
In the course of use a chain will extend (i.e. the pins will use leading to extension of the chain). Employing a chain which has been stretched far more than the earlier mentioned optimum allowance triggers the chain to trip up the enamel of the sprocket. This leads to hurt to the guidelines of the chainwheels teeth, as the force transmitted by the chain is transmitted completely by way of the leading of the tooth, rather than the total tooth. This results in serious donning of the chainwheel.
FOR CHAIN STHangZhouRDS
Requirements businesses (these kinds of as ANSI and ISO) maintain expectations for layout, dimensions, and interchangeability of transmission chains. For example, the adhering to Desk shows information from ANSI standard B29.1-2011 (Precision Power Transmission Roller Chains, Attachments, and Sprockets) designed by the American Society of Mechanical Engineers (ASME). See the references[8][9][10] for added info.

For mnemonic reasons, under is one more presentation of crucial dimensions from the same regular, expressed in fractions of an inch (which was component of the considering powering the option of desired quantities in the ANSI regular):
| Pitch (inches) | Pitch expressed in eighths |

| 5⁄8 | 5⁄eight | five | 3⁄eight |
| three⁄four | six⁄eight | 6 | one⁄two |
| 1 | eight⁄eight | eight | five⁄eight |
Notes:
one. The pitch is the distance in between roller centers. The width is the length in between the website link plates (i.e. slightly much more than the roller width to permit for clearance).
2. The correct-hand digit of the common denotes 0 = normal chain, 1 = lightweight chain, 5 = rollerless bushing chain.
3. The still left-hand digit denotes the number of eighths of an inch that make up the pitch.
four. An “H” subsequent the regular variety denotes heavyweight chain. A hyphenated number following the normal variety denotes double-strand (2), triple-strand (3), and so on. As a result 60H-3 denotes variety sixty heavyweight triple-strand chain.
A standard bicycle chain (for derailleur gears) uses narrow 1⁄2-inch-pitch chain. The width of the chain is variable, and does not impact the load ability. The more sprockets at the rear wheel (historically 3-6, today 7-twelve sprockets), the narrower the chain. Chains are sold according to the number of speeds they are created to perform with, for example, “10 pace chain”. Hub gear or one speed bicycles use 1/2″ x 1/8″ chains, exactly where 1/8″ refers to the maximum thickness of a sprocket that can be utilized with the chain.
Generally chains with parallel formed back links have an even quantity of links, with each and every narrow url adopted by a broad 1.Chains created up with a uniform variety of url, narrow at 1 and wide at the other end, can be made with an odd number of links, which can be an benefit to adapt to a special chainwheel-length on the other facet such a chain tends to be not so sturdy.
Roller chains produced employing ISO regular are sometimes called as isochains.

It is crucial if you are setting up the chainwheels by yourself to have the factory service handbook particular to your design. Our chainwheels are manufactured to be a direct CZPT for your OEM chainwheels and as this sort of, the installation ought to be carried out according to your types service manual.
During use a chain will stretch (i.e. the pins will dress in causing extension of the chain). Making use of a chain which has been stretched more than the over optimum allowance triggers the chain to journey up the enamel of the sprocket. This brings about injury to the ideas of the chainwheels tooth, as the pressure transmitted by the chain is transmitted totally via the prime of the tooth, rather than the complete tooth. This outcomes in serious wearing of the chainwheel.
FOR CHAIN STHangZhouRDS
Requirements companies (such as ANSI and ISO) keep standards for design and style, proportions, and interchangeability of transmission chains. For illustration, the subsequent Desk shows knowledge from ANSI standard B29.1-2011 (Precision Power Transmission Roller Chains, Attachments, and Sprockets) developed by the American Culture of Mechanical Engineers (ASME). See the references[8][9][10] for extra info.

For mnemonic reasons, below is yet another presentation of essential proportions from the exact same regular, expressed in fractions of an inch (which was element of the considering driving the decision of chosen quantities in the ANSI standard):
| Pitch (inches) | Pitch expressed in eighths |
ANSI regular chain quantity |
Width (inches) |
|---|---|---|---|
| 1⁄four | two⁄8 | 25 | one⁄eight |
| 3⁄8 | 3⁄8 | three5 | 3⁄16 |
| one⁄2 | 4⁄eight | fourone | 1⁄4 |
| 1⁄2 | 4⁄eight | 4 | five⁄16 |
| 5⁄8 | five⁄8 | 5 | three⁄eight |
| 3⁄four | 6⁄eight | six | 1⁄two |
| 1 | eight⁄8 | 8 | 5⁄8 |
Notes:
one. The pitch is the length between roller centers. The width is the distance between the hyperlink plates (i.e. somewhat much more than the roller width to let for clearance).
2. The correct-hand digit of the common denotes 0 = typical chain, 1 = light-weight chain, 5 = rollerless bushing chain.
three. The left-hand digit denotes the amount of eighths of an inch that make up the pitch.
4. An “H” pursuing the regular quantity denotes heavyweight chain. A hyphenated variety subsequent the common quantity denotes double-strand (2), triple-strand (3), and so on. Thus 60H-3 denotes variety sixty heavyweight triple-strand chain.
A standard bicycle chain (for derailleur gears) employs slender 1⁄2-inch-pitch chain. The width of the chain is variable, and does not impact the load ability. The much more sprockets at the rear wheel (historically 3-6, presently 7-twelve sprockets), the narrower the chain. Chains are offered in accordance to the amount of speeds they are created to work with, for illustration, “ten speed chain”. Hub gear or one pace bicycles use 1/2″ x 1/8″ chains, where 1/8″ refers to the highest thickness of a sprocket that can be employed with the chain.
Normally chains with parallel shaped back links have an even variety of back links, with each and every narrow hyperlink followed by a broad 1.Chains built up with a uniform kind of website link, slender at 1 and broad at the other conclude, can be made with an odd quantity of backlinks, which can be an edge to adapt to a special chainwheel-distance on the other aspect such a chain tends to be not so sturdy.
Roller chains created employing ISO normal are sometimes named as isochains.
