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.

Split-Tapered Bushing-Bore Sprockets for ANSI Roller Chain


Since these sprockets grip bushings more tightly than taper-lock sprockets, they’re often used in high-torque applications. The same sprocket can be used with different shaft diameters; choose a compatible split-tapered bushing with the bore size you need.
Sprockets for P1- and Q1-Style bushings have a keyway that fits a matching key on the bushing.
