Flat Sprockets for Metric Roller Chain
With metric teeth and slim profile, these sprockets allow your ISO roller chain to reach narrow spaces. They're commonly referred to as A-plate sprockets. Machine the unfinished bore to fit your shaft—sprockets come machined to the shaft diameter listed and are machinable up to the maximum shaft diameter size. Sprockets meet DIN 8187 and ISO 606, international standards for sprockets and roller chains.

Idler Sprockets for ANSI Roller Chain
Maintain constant tension on your drive with these sprockets that press against your chain to take up slack and reduce wear and vibration. They rotate freely on built-in bearings and are for use with roller chain tensioners. Bearings are double sealed to keep dirt out.

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. Sleeve bearings are self-lubricating.

Idler Sprockets for Metric Roller Chain
Keep constant tension on your drive with these sprockets that press against your metric ISO roller chain to take up slack and reduce wear and vibration. They rotate freely on built-in ball bearings, which are double sealed to keep dirt out, and are for use with roller chain tensioners. All come with a finished bore that fits directly onto your shaft—no need for machining. These sprockets meet ISO 606, which is an international standard for dimensions and materials.
