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.

These pulleys are cast iron.

A built-in spring maintains tension on your belt.

Teeth are curved and set in an offset pattern for high strength with 25% less operating noise than pulleys and belts with trapezoidal teeth.

Curved teeth with a high pitch provide superior load distribution and reduce wear. They mount with a bushing for a more secure grip on the shaft than set screws.
