Add these free-spinning pulleys to your timing belt setup to minimize vibration and keep belts from wearing out. The needle bearing at the center of these pulleys is lined with small, cylindrical rollers that reduce friction as they rotate. This bearing allows both the pulley and the shaft it’s mounted on to spin independently. Made from iron or steel, these pulleys are strong and wear-resistant. The black oxide coating protects the pulleys from corrosion in dry environments.

Trapezoidal teeth on the outside of the pulley fit into teeth inside your timing belt—select a pulley that matches your belt trade size. The maximum belt width should be the same size or larger than the width of your timing belt.
