Flat Sprockets for ANSI Roller Chain
Also known as A-plate and weld sprockets, these have a slim profile that fits in narrow spaces and are often welded directly to a shaft.They come machined to the shaft diameter size listed and are machinable up to the maximum shaft diameter size.

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.
