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.

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.

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

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

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

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.

Anodized aluminum has good corrosion resistance.

Made of aluminum, these pulleys have good corrosion resistance.

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

To prevent slippage while moving extra heavy loads, these pulleys mount with a bushing for a more secure grip on the shaft than set screws and press-fit pulleys.

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

Mount these high torque drive (HTD) pulleys onto a hex shaft.

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

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.

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

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