Taper-Lock Bushing-Bore V-Belt Drive Pulleys

Mount these drive pulleys with a taper-lock bushing for a tight, wobb le-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 drive pulley can be used with different shaft diameters.

Adjustable-Speed V-Belt Drive Pulleys


3 Grooves

Also known as step-cone pulleys, these have multiple groove sizes so you can quickly change rotation speed by moving your belt to a different groove. Use with fractional-horsepower motors for drives with frequent speed changes.

V-Belt Idler Pulleys


3 Grooves

These idler pulleys spin freely on built-in ball bearings to maintain tension for reduced wear and vibration. Commonly used with belt tensioners (sold separately), they are lightweight and corrosion and abrasion resistant. Bearings are double sealed to keep dirt out.
