FAQ Group: Roller Chain FAQ's

How is proper chain tension measured and why is it important?

Proper chain tension is critical to achieving acceptable service life, as excessive tension can cause accelerated wear or chain overload and excessive slack can cause rough chain operation and possibly result in the chain skipping a sprocket tooth, resulting in …

What is roller chain length matching and why is it used?

Many applications require two or more chains, normally with attachments, to run in parallel with “flights” joining the chains together forming a conveyor- or transfer-type system. In these cases, it is critical to have the chains ordered as a set, …

What is the difference between riveted and cottered chain?

Riveted chain is constructed using pins that extend through the plate on each side and are then riveted, or sidemashed, on their ends to add some additional strength to the hold between the pin and plate. Note: the riveting, or …

What are the temperature limitations of Diamond roller chain?

Carbon steel chains can routinely be used where temperatures are between 0 and 350 degrees Fahrenheit. For applications where temperatures are greater than 350 degrees, chain with extra clearance in some of the components and a special synthetic high temperature …

Why is my chain “stretching,” or elongating, too quickly?

Proper lubrication is critical in achieving the maximum wear life of any roller chain. As the chain articulates around the sprockets, the pin and bushing wear. This wearing causes the elongation, or “stretch,” in the chain. Lubrication of these surfaces …

My roller chain is rusting in service. What should I do?

Review the drive requirements and surroundings. For chains requiring no rusting and being used in acidic or caustic environments, consider using stainless steel chains. For chains exposed to moisture only, consider using plated chains (such as Diamond ACE or Nickel …
