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

Designed for large belt and chain drives, these tensioners maintain correct drive tension for smooth operation, maximum power, and a long service life.

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

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

Mount these tensioners directly onto your chain drive. They have adjustable straps that take up slack and apply constant tension.

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

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

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

Made of aluminum, these pulleys have good corrosion resistance.

Made of aluminum, these pulleys have good corrosion resistance.

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

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

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

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.

Use these pulleys with compatible quick-disconnect bushings.

Choose from nylon, UHMW, and zinc.

Increase efficiency, vary speed, and extend the life of your drive by changing the pitch on these pulleys.

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.

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