Taper-Lock Bushing-Bore V-Belt Pulleys
3 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.

Adjustable-Speed V-Belt Pulleys
3 Grooves
4 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.
