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.

Precisely apply tension in a straight line by moving the adjustment screw.

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

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

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

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

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.

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

Made of aluminum, these pulleys have good corrosion resistance.

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

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.

These HTD (high torque drive) pulleys have a curved tooth shape that provides higher strength than trapezoidal teeth.

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 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.

Mount these pulleys with a taper-lock bushing for a tight, wobble-free hold on your shaft.

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

Use on a conveyor pulley with a conveyor belt tensioner to adjust the tension on a conveyor belt.
