Belts and Pulleys

Heavy Duty V-Belt Pulleys

These pulleys are cast iron.

V-Belt Pulleys

Choose from nylon, UHMW, and zinc.

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.

Constant-Tension V-Belt Pulleys

A built-in spring maintains tension on your belt.

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.

XL Series Lightweight Timing Belt Pulleys

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

XL Series Dust-Free Timing Belts

Abrasion-resistant urethane means these belts don’t create dust while they run.

XL Series Dust-Free Cut-to-Length Timing Belts

Drive linear motion while maintaining a clean environment—urethane has excellent abrasion resistance so these belts don’t create dust while they run. They have Kevlar reinforcement, which has very high strength, low stretch, and excellent shock resistance.

L Series Dust-Free Timing Belts

Urethane has excellent abrasion resistance, so these belts don’t create dust while they run.

L Series Dust-Free Cut-to-Length Timing Belts

Known for excellent abrasion resistance, use one of these urethane belts in your linear motion application to don’t create dust while they run. Belts have Kevlar reinforcement, which has very high strength, low stretch, and excellent shock resistance.

MXL Series Lightweight Timing Belt Pulleys

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

MXL Series Dust-Free Timing Belts

Urethane has excellent abrasion resistance, so these belts don’t create dust while they run. They have Kevlar reinforcement, which has very high strength, low stretch, and excellent shock resistance.

T Series Dust-Free Timing Belts

Belts are abrasion-resistant urethane, so they don’t create dust while they run. They have steel reinforcement, which has very high strength, low stretch, and excellent shock resistance.

H Series Dust-Free Timing Belts

Urethane has excellent abrasion resistance, so these belts don’t create dust while they run. Belts have steel reinforcement, which has very high strength, low stretch, and excellent shock resistance.

H Series Dust-Free Cut-to-Length Timing Belts

Known for excellent abrasion resistance, use a urethane belt in your linear motion application to avoid dust from wear. They have Kevlar reinforcement, which has very high strength, low stretch, and excellent shock resistance.

AT Series Dust-Free Timing Belts

Made of urethane, these belts have excellent abrasion resistance, so they don’t create dust while they run.

AT Series Dust-Free Cut-to-Length Timing Belts

Urethane has excellent abrasion resistance, so these belts don’t create dust while they run. They have steel reinforcement, which has very high strength, low stretch, and excellent shock resistance.
