Worm gears use screw threads to reduce shaft speed by ratios of 10:1 and greater while transmitting motion at a right angle.

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.

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.

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 have the same sizing versatility as quick-disconnect pulleys, but they create a tighter grip on bushings for use in high-torque applications.

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