V-Belt Pulleys

Choose from nylon, UHMW, and zinc.

Heavy Duty V-Belt Pulleys

These pulleys are cast iron.

Constant-Tension V-Belt Pulleys

A built-in spring maintains tension on your belt.

Adjustable-Pitch V-Belt Pulleys

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

Adjustable-Speed V-Belt Pulleys

Also known as step-cone pulleys, these have multiple groove sizes so you can quickly change rotation speed by moving your belt to a different groove.

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

Use these pulleys with compatible quick-disconnect bushings.

Taper-Lock Bushing-Bore V-Belt Pulleys

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

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.

V-Belt Idler Pulleys

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

V-Belt and Pulley Trade Size Identifiers

Measure V-belt cross sections and pulley groove depths to select the correct size belt.

High-Strength Timing Belts and Pulleys

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 HTD Timing Belt Pulleys

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

High-Strength Corrosion-Resistant
HTD Timing Belt Pulleys

Move belts forward and backward or stop and start them in precise positions, especially in areas where rust is a concern.

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.

Ultra-High-Strength Poly Chain Timing Belt Pulleys

Curved teeth with a high pitch provide superior load distribution and reduce wear. They mount with a bushing for a more secure grip on the shaft than set screws.

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.

Timing Belts and Pulleys

XL Series Corrosion-Resistant Timing Belt Pulleys

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

XL Series Timing Belt Pulleys

Pulleys are XL series (extra light) and have trapezoidal teeth.

XL Series Lightweight Timing Belt Pulleys

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

L Series Corrosion-Resistant Timing Belt Pulleys

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

L Series Timing Belt Pulleys

These L series (light) pulleys and have trapezoidal teeth.

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.

MXL Series Corrosion-Resistant Timing Belt Pulleys

Anodized aluminum has good corrosion resistance.

MXL Series Lightweight Timing Belt Pulleys

Made from polycarbonate, these pulleys are useful in applications with weight constraints.

Timing Belt Idler Pulleys

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

T Series Timing Belt Pulleys

Made of aluminum, these pulleys have good corrosion resistance.

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.

H Series Timing Belt Pulleys

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

AT Series Timing Belt Pulleys

Made of aluminum, these pulleys have good corrosion resistance.

Round-Belt Pulleys

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

Round-Belt Idler Pulleys

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

Flat-Belt Pulleys

Flat-Belt Idler Pulleys

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

Flat-Belt Pulleys

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

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.

Mounted Pulleys for Wire Rope—For Horizontal Pulling

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

Hanging Pulleys for Wire Rope—For Horizontal Pulling

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

Easy-Open Hanging Pulleys for
Wire Rope—For Horizontal Pulling

Also known as snatch blocks, these open so it’s easier to feed the rope through the housing—a free rope end is not needed.

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

Machinable Pulleys

Customize the groove and bore to fit your application.

Pulley Diameter Checkers

Also known as groove gauges, these measure the groove of your pulley to check for wear as well as determine the correct wire rope size.

Building and Machinery Hardware

Chain-Operated Wheels for Overhead Valves

Open and close almost any hand-wheel operated overhead valve from the floor. These wheels can also be used to operate hatches, skylights, and other overhead components.

Impact-Resistant Chain-Operated
Wheels for Overhead Valves

Made of high-strength ductile iron, these wheels withstand impact better than other wheels to open and close large or stubborn overhead valves from the floor. They can also be used to operate hatches, skylights, and other overhead components.

Overhead Door Openers

Pull a chain to manually open overhead doors.

Belt Conveyors

Steel Pulleys for Conveyor Belts

Replace worn or damaged pulleys or create new belt conveyors.

Stainless Steel Pulleys for Conveyor Belts

The corrosion-resistant stainless steel construction makes these pulleys suitable for washdown applications.

Rubber-Coated Pulleys for Conveyor Belts

A rubber coating, also known as lagging, increases friction for a better grip on the belt.

Retainer-Mount Coating for Conveyor Pulleys

Slide these coating strips into metal retainers that you attach to your pulley—they add friction that helps conveyor belts stay on pulleys and are replaceable when they’re worn.
