V-Belt Pulleys

Quick-Disconnect (QD) Bushing-Bore V-Belt Pulleys

Use these pulleys with compatible quick-disconnect bushings.

Split-Tapered Bushing-Bore V-Belt 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.

Taper-Lock Bushing-Bore V-Belt Pulleys

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

Heavy Duty V-Belt Pulleys

These pulleys are cast iron.

Adjustable-Pitch V-Belt Pulleys

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

Constant-Tension V-Belt Pulleys

A built-in spring maintains tension on your belt.

Timing Belts and Pulleys

L Series Quick-Disconnect Timing Belt Pulleys

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

H Series Quick-Disconnect Timing Belt Pulleys

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

Timing Belt Idler Pulleys

Add these free-spinning pulleys to your timing belt setup to minimize vibration and keep belts from wearing out.

High-Strength HTD Timing Belt Pulleys

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

High-Strength HTD Timing Belt Idler Pulleys

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.

High-Strength GT Timing Belt Pulleys

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.

High-Strength Ultra-Quiet Timing Belt Pulleys

Teeth are curved and set in an offset pattern for high strength with 25% less operating noise than pulleys and belts with trapezoidal teeth.

Flat-Belt Idler Pulleys

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

Pulleys—For Horizontal Pulling

Pulleys for Wire Rope—For Horizontal Pulling

Also known as sheaves, use these pulleys to assist with horizontal pulling or to guide a rope.

Pulleys for Rope—For Horizontal Pulling

Also known as sheaves, use these pulleys to assist with horizontal pulling or to guide a rope.

Mounted Pulleys for Rope—For Horizontal Pulling

Mount these pulleys to a flat surface to assist with horizontal pulling or to guide a rope.

Hanging Pulleys for Rope—For Horizontal Pulling

Hang these pulleys from hooks, screws, and bolts to assist with horizontal pulling or to guide a rope.
