The chain spocket, as a drive or deflection for chains, has pockets to hold the chain links with a D-profile cross section with flat side surfaces  parallel to the centre plane of the chain links, and outer surfaces at right angles to the chain link centre plane. The chain links are pressed firmly against the outer surfaces and each of the side surfaces by the angled laying surfaces at the base of the pockets, and also the support surfaces of the wheel body together with the end sides of the webs formed by the leading and trailing walls of the pocket.


When fitting new chainwheels it is very important that a new chain is fitted at the same time, and vice versa. Using an old chain with new sprockets, or a new chain with old sprockets will cause rapid wear.

It is important if you are installing the chainwheels yourself to have the factory service manual specific to your model. Our chainwheels are made to be a direct replacement for your OEM chainwheels and as such, the installation should be performed according to your models service manual.

During use a chain will stretch (i.e. the pins will wear causing extension of the chain). Using a chain which has been stretched more than the above maximum allowance causes the chain to ride up the teeth of the sprocket. This causes damage to the tips of the chainwheels teeth, as the force transmitted by the chain is transmitted entirely through the top of the tooth, rather than the whole tooth. This results in severe wearing of the chainwheel.


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):

Pitch (inches) Pitch expressed
in eighths

chain number
Width (inches)
14 28 25 18
38 38 35 316
12 48 41 14
12 48 40 516
58 58 50 38
34 68 60 12
1 88 80 58

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.

gear chain

How does a gear chain handle different speeds and loads?

A gear chain is designed to handle different speeds and loads by incorporating specific features and materials:

1. Gear Ratio Selection:

– The gear ratio is the ratio of the number of teeth on the driving gear to the number of teeth on the driven gear. By selecting the appropriate gear ratio, the speed and torque can be adjusted to match the requirements of the application. Higher gear ratios provide lower speed and higher torque, while lower gear ratios offer higher speed and lower torque.

2. Gear Tooth Design:

– The tooth design of a gear chain is optimized to distribute the load evenly across the teeth. This ensures that each tooth can handle its share of the load without excessive stress concentration. The tooth profile and pitch are carefully calculated to provide efficient power transmission and minimize wear.

3. Material Selection:

– Gear chains are typically made from high-strength materials, such as alloy steel or hardened steel, to withstand the loads and stresses imposed on them. The material selection is based on the anticipated loads and the desired durability of the chain. Heat treatment processes, such as quenching and tempering, are often employed to further enhance the strength and toughness of the chain.

4. Lubrication:

– Proper lubrication is crucial for the smooth operation and longevity of a gear chain. Lubricants reduce friction and wear between the gear teeth, allowing the chain to handle higher speeds and loads with reduced heat generation. Lubrication also helps to prevent corrosion and extend the chain’s service life.

5. Chain Tension:

– Maintaining proper chain tension is essential for optimal performance. Adequate tension ensures proper engagement of the gear teeth and prevents excessive slack or binding. Chain tensioners or tensioning devices may be used to adjust the tension and compensate for any elongation or wear that occurs over time.

6. System Design:

– The overall design of the gear chain system, including the selection of supporting components such as gears, bearings, and shafts, plays a vital role in handling different speeds and loads. The system must be engineered to provide adequate strength, alignment, and support to ensure reliable operation under varying conditions.

By carefully considering gear ratio selection, tooth design, material selection, lubrication, chain tension, and system design, a gear chain can effectively handle different speeds and loads. It provides efficient power transmission and reliable performance in a wide range of applications.

How do you ensure proper tensioning and alignment of a gear chain?

Proper tensioning and alignment are crucial for the optimal performance and longevity of a gear chain. Here are the steps to ensure proper tensioning and alignment:

1. Tensioning:

– Follow the manufacturer’s guidelines: Refer to the gear chain manufacturer’s specifications and recommendations for the appropriate tensioning method and tension level.

– Use a tensioning device: Utilize a tensioning device, such as a tensioner or tensioning tool, to apply the correct tension to the gear chain.

– Measure tension: Use a tension gauge to measure the tension in the gear chain. Compare the measured tension with the recommended tension specified by the manufacturer.

– Adjust tension: If the measured tension is too low or too high, adjust the tensioning device accordingly to achieve the recommended tension level.

2. Alignment:

– Check alignment: Inspect the alignment of the gear chain by visually examining the positioning of the sprockets or gears. They should be properly aligned and in the same plane.

– Use alignment tools: Utilize alignment tools, such as alignment indicators or laser alignment systems, for precise alignment measurements.

– Adjust alignment: If misalignment is detected, make necessary adjustments to align the sprockets or gears properly. This may involve adjusting the mounting positions or shimming to achieve the desired alignment.

– Verify alignment: After making adjustments, recheck the alignment using the alignment tools to ensure accurate alignment of the gear chain.

Regular inspection and maintenance are essential to ensure continued proper tensioning and alignment of the gear chain. Monitor the tension and alignment periodically and make adjustments as needed to maintain optimal performance and minimize wear and fatigue.

How does a gear chain differ from other types of chains?

A gear chain differs from other types of chains in the way it operates and its specific design features:

– Gear Engagement: Unlike standard roller chains or silent chains that rely on the interaction between pins and rollers or plates, a gear chain utilizes gear teeth on the chain links that directly engage with the teeth of the sprockets. This positive engagement provides a secure and efficient transfer of torque.

– Speed Control: Gear chains offer precise speed control due to the gear teeth engagement. By varying the size and number of teeth on the sprockets, the speed ratio between the driving and driven shafts can be accurately adjusted to meet specific application requirements.

– Load Capacity: Gear chains are designed to handle higher loads compared to other types of chains. The gear teeth engagement distributes the load evenly across the chain, resulting in improved load-carrying capacity and resistance to fatigue.

– Compact Design: Gear chains have a more compact design compared to other types of chains. The gear teeth are integrated into the chain links, eliminating the need for separate components like pins, rollers, or plates. This compact design allows for efficient power transmission in applications with limited space.

– Specific Applications: Gear chains are commonly used in mechanical systems that require precise speed control and high load-carrying capacity. They are often found in machinery, automotive systems, robotics, and other applications where accurate power transmission is critical.

– Lubrication: Gear chains typically require lubrication to minimize friction and wear between the gear teeth. Proper lubrication ensures smooth operation and extends the chain’s service life.

In summary, gear chains differ from other types of chains in terms of their gear engagement, precise speed control, higher load capacity, compact design, suitability for specific applications, and lubrication requirements.
