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.

High-Strength HTD Timing Belt Idler Pulleys
Keep high torque drive (HTD) timing belt systems running tightly with these idler pulleys. Made with built-in, free-spinning ball bearings, they're installed on shafts or belt tensioners (not included) to remove slack from timing belts. By maintaining tension on the belt, these pulleys reduce wear and vibration in 3D printing, machine tool drives, robotics, and other linear motion applications that require precise positioning.
When replacing an idler pulley, be sure the pulley matches your belt's trade size.
Toothed pulleys are shaped to mesh with the teeth on a timing belt, which reduces wear on the belt's teeth.
Iron pulleys are strong and wear resistant, with a black oxide coating that protects them from corrosion in dry environments.
