These sprockets are made of steel.

Hardened teeth give these steel sprockets increased wear resistance for a long service life.

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.

These pulleys spin freely on built-in ball bearings to maintain tension for reduced wear and vibration.

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 to remove slack from timing belts.
