Heavy Duty V-Belt Pulleys

These pulleys are cast iron.

V-Belt Pulleys

Choose from nylon, UHMW, and zinc.

Adjustable-Pitch V-Belt Pulleys

Increase efficiency, vary speed, and extend the life of your drive by changing the pitch on these pulleys.

Adjustable-Speed V-Belt Pulleys

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.

Constant-Tension V-Belt Pulleys

A built-in spring maintains tension on your belt.

Quick-Disconnect (QD) Bushing-Bore V-Belt Pulleys

Use these pulleys with compatible quick-disconnect bushings.

Taper-Lock Bushing-Bore V-Belt Pulleys

Mount these pulleys with a taper-lock bushing for a tight, wobble-free hold on your shaft.

Split-Tapered Bushing-Bore V-Belt Pulleys

These pulleys have the same sizing versatility as quick-disconnect pulleys, but they create a tighter grip on bushings for use in high-torque applications.

V-Belt Idler Pulleys

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