About Sizing Belts

Twist the tabbed links together to form a belt. Because it’s made of individual links, this belting allows you to change your belt length without dismantling your drive.

Taper-Lock Bushing-Bore V-Belt Pulleys

1 Groove

2 Grooves

3 Grooves

4 Grooves

Mount these pulleys with a taper-lock bushing for a tight, wobble-free hold on your shaft. These pulleys transfer force from the shaft to a V-belt in a power transmission system, and also help with misalignment. Made of cast iron, these pulleys are durable and resist wear.

Depending on the taper-lock bushing you choose, the same pulley can be used with different shaft diameters.
