Wear-Resistant Wide-Hub Idler Sprockets for ANSI Roller Chain
Hardened teeth give these steel sprockets increased wear resistance for a long service life. The wide hub provides stability under heavy loads. Designed to rotate freely on built-in bearings, idler sprockets maintain constant tension on your drive by pressing against your chain to take up slack and reduce wear and vibration. They are for use with roller chain tensioners.

ANSI Roller Chain and Links
Connecting links are also known as master links. They're used to join the ends of a chain length. The side plate is easy to remove for attaching to a chain. Adding links are also known as roller links. They require two connecting links to join chain. Adding-and-connecting links are also known as half links and offset links. A combination of connecting and adding links, they join chain that requires an odd number of links. For trade number 35 and up, the side plate is easy to remove for attaching them to chain.

Heavy Duty ANSI Roller Chain and Links
Thick side plates allow this chain to handle greater shock loads, like start/stop applications, than standard chain.
Connecting links are also known as master links. They're used to join the ends of a chain length. The side plate is easy to remove for attaching to a chain. Adding links are also known as roller links. They require two connecting links to join chain. Adding-and-connecting links are also known as half links and offset links. A combination of connecting and adding links, they can join chain that requires an odd number of links. The side plate is easy to remove for attaching to chain.
