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

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.

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

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

Anodized aluminum has good corrosion resistance.

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.

Pulleys are H series (heavy) and have trapezoidal teeth.

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.

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

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

These pulleys are cast iron.

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

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.

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.

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.

Housing is brass.

Check how much force a part can take before it bends, stretches, or breaks.

Measure tension force as well as weight.

Measure the force needed to carry out tasks in your facility, such as pushing carts, pulling pallet trucks, or lifting containers.

Measure tension force as well as weight. Also known as dynamometers.

Read tension and compression measurements with a glance—these gauges have three color-coded indicator lights to show you if a part is at your desired force. Red means the force is too high, orange means too low, and green is just right.
