Apply continuous tension and automatically take up slack at any point in a 180° arc.

Position the adjustment arm to control tension in a 360° arc.

Able to fit in tight spots, these tensioners are less than 3" tall.

At less than 4" in height, these tensioners are good for use on low-clearance drives.

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

Pulleys are anodized aluminum, which is more corrosion resistant than steel.

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

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

Pulleys are anodized aluminum, which is more corrosion resistant than steel.

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

Made from polycarbonate, these pulleys are useful in applications with weight constraints.

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.

Move belts forward and backward or stop and start them in precise positions, especially in areas where rust is a concern.

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.

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 these pulleys with compatible quick-disconnect bushings.

Mount these pulleys directly onto a shaft to transmit rotary motion and torque.
