Pulleys are XL series (extra light) and have trapezoidal teeth.

Acetal and aluminum construction makes these pulleys useful in for weight-sensitive applications.

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

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.

Anodized aluminum has good corrosion resistance.

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.

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.

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.

These pulleys are cast iron.

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.

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.

Also known as paper-plant pulleys, these are made of a paper-fiber composite that minimizes belt slippage and wear.
