Carry heavy loads without slippage—pulleys mount with a bushing for a more secure grip on the shaft than set screws.

Add these free-spinning pulleys to your timing belt setup to minimize vibration and keep belts from wearing out.

Made of iron, these pulleys are strong enough to carry extra heavy loads.

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.

For higher speed or higher torque applications, these GT series timing belt pulleys provide a more precise fit than HTD pulleys. Use them where accuracy is critical, such as in storage and retrieval systems or in robotics.

These pulleys are cast iron.

A built-in spring maintains tension on your belt.

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.
