Idler Roller Chain Sprockets

Discover a wide array of shaft couplings, chains and sprockets, belts and sheaves, and drive components.
Idler roller chain sprockets guide chain, decrease vibration, and maintain proper chain tension. They have spring-tensioned arms that mount the sprocket and keep the chain tight but not overly tight. They also have hubs that house bushings, which allows the sprocket to spin freely on the shaft.
