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.

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

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.
