Lightweight Idler Sprockets for ANSI Roller Chain
Made of nylon, these sprockets are lightweight, quiet, and corrosion resistant. 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. Bearings are double sealed to keep dirt out.
