About Roller Chain and Sprockets

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.
