Wear-Resistant Idler Sprockets for ANSI Roller Chain


Hardened teeth give these steel sprockets increased wear resistance for a long service life. 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.
Ball bearings are double sealed to keep dirt out.
