About Roller Chain and Sprockets

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.
