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.

Pulleys for Wire Rope—For Lifting

Use the bore to mount these pulleys on a shaft. These pulleys are also known as sheaves.

Mounted Pulleys for Wire Rope—For Lifting

Mount these pulleys to a flat surface.

Round-Belt Pulleys

Round-Belt Idler Pulleys

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

Round-Belt Pulleys

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

V-Belt Pulleys

Heavy Duty V-Belt Pulleys

These pulleys are cast iron.

V-Belt Pulleys

Choose from nylon, UHMW, and zinc.

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.

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.

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.

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

Use these pulleys with compatible quick-disconnect bushings.

V-Belt Idler Pulleys

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

Timing Belts and Pulleys

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.

XL Series Corrosion-Resistant Timing Belt Pulleys

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

MXL Series Lightweight Timing Belt Pulleys

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

MXL Series Corrosion-Resistant Timing Belt Pulleys

Anodized aluminum has good corrosion resistance.

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.

H Series Timing Belt Pulleys

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

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.

T Series Timing Belt Pulleys

Made of aluminum, these pulleys have good corrosion resistance.

AT Series Timing Belt Pulleys

Made of aluminum, these pulleys have good corrosion resistance.

High-Strength Timing Belts and Pulleys

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 HTD Timing Belt Pulleys

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

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 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 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.

Flat-Belt Idler Pulleys

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

Track Rollers

Shaft-Mount V-Groove Track Rollers

Also known as yoke-style cam followers, these rollers have more mounting flexibility than threaded track rollers. They're typically mounted onto a shaft or clevis rod end.

Threaded V-Groove Track Rollers

Thread the stud directly into a component or secure with a nut for through-hole mounting.

Sanitary Threaded V-Groove Track Rollers

Guide loads along angle rail tracks in food and pharmaceutical plants or other sanitary environments.

Sanitary Shaft-Mount V-Groove Track Rollers

Support and guide loads on angle rails in food, pharmaceutical, and other sanitary environments. Also known as yoke-style cam followers, these track rollers offer more mounting flexibility than threaded alternatives and are typically mounted on shafts and clevis rod ends.

Threaded V-Groove Track
Rollers with Adjustable Shoulder

Also known as eccentric track rollers, the shoulder adjusts up or down to align to your track, enabling uniform alignment among rollers in a system.

Double-Flanged Track Rollers

A dual-flange design provides guidance on both sides and helps these rollers stay on track.

Casters and Wheels

V-Groove Track Wheels

These wheels have a 90° V-groove and a flat tread to move your equipment on angle-iron track as well as the floor.

Cut-to-Width Polyurethane Wheels

Make your own wheels by cutting these wheel blanks to size with a band saw. They're easy to machine so you can create V-groove and flanged wheels, as well as conveyor rollers and pulleys.

Extra-High-Capacity V-Groove
Track Casters with Metal Wheels

The wheels of these casters have a 90° V-groove and a flat tread to move your equipment on angle-iron track as well as the floor.

High-Capacity V-Groove Wheel
Track Casters with Metal Wheels

The wheels of these casters have a 90° V-groove and a flat tread to move your equipment on angle-iron track as well as the floor.

High-Capacity Corrosion-Resistant V-Groove
Wheel Track Casters with Metal Wheels

The wheels of these casters have a 90° V-groove and a flat tread to move your equipment on angle-iron track as well as the floor. The 303 stainless steel wheels are suitable for steam-cleaning applications.

V-Groove Wheel Track Casters
with Polyurethane Wheels

The wheels of these casters have a 90° V-groove and a flat tread to move your equipment on angle-iron track as well as the floor.

Corrosion-Resistant V-Groove Wheel
Track Casters with Polyurethane Wheels

The wheels of these casters have a 90° V-groove and a flat tread to move your equipment on angle-iron track as well as the floor. Polyurethane wheels combine the abrasion resistance of plastic with the shock- and sound-absorbing qualities of rubber. Their 304 stainless steel frame is corrosion resistant.
