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

These pulleys are cast iron.

A built-in spring maintains tension on your belt.

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.

Keep high torque drive (HTD) timing belt systems running tightly with these idler pulleys. Made with built-in, free-spinning ball bearings, they're installed on shafts or belt tensioners to remove slack from timing belts.

To prevent slippage while moving extra heavy loads, these pulleys mount with a bushing for a more secure grip on the shaft than set screws and press-fit pulleys.

Securely carry heavy loads—these pulleys mount with a bushing for a better grip on the shaft than set screws and press-fit pulleys.
