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.

XH Series Timing Belts

Quiet-running neoprene is reinforced with high-strength fiberglass to move extra heavy loads with little noise.

XXH Series Timing Belts

Known as double extra heavy duty belts, these XXH belts move heavy loads.

High-Strength Timing Belts and Pulleys

High-Strength HTD Timing Belts

HTD (high torque drive) timing belts have a curved tooth shape that provides higher strength than trapezoidal teeth. Belts are neoprene with fiberglass reinforcement for quiet operation.

High-Strength HTD Cut-to-Length Timing Belts

Curved teeth made from fiberglass-reinforced neoprene make these HTD (high-torque drive) belts stronger and quieter than belts with trapezoidal teeth.

High-Strength Ultra-Quiet Timing Belts

These quiet-running timing belts have a curved tooth shape that provides higher strength than trapezoidal teeth.

Ultra-High-Strength Poly Chain Timing Belts

Strong enough to replace roller chain, these timing belts combine the high strength of a curved tooth with high-strength carbon fiber reinforcement.

V-Belts

The trapezoidal shape allows these belts to wedge into pulleys in the presence of misalignment.

High-Capacity Narrow-Wedge V-Belts

A narrow belt profile transmits up to three times the horsepower of standard V-belts for use on heavy duty drives with shock loads.

Precision-Matched V-Belts

Ensure even load distribution on drives with multiple belts.

Cogged V-Belts

More flexible than smooth V-belts, these have notches that allow them to bend around small-diameter pulleys and accommodate twists and turns on curved drives.

High-Capacity Narrow-Wedge Cogged V-Belts

A narrow belt profile transmits up to three times the horsepower of standard cogged V-belts for use on heavy duty drives with shock loads.

Cogged V-Belts for Variable-Speed Pulleys

A wide profile allows these belts to ride up and down the groove in variable-speed pulleys to handle a wide range of speed ratios.

Ultra-Flexible Banded V-Belts

An extremely thin profile gives these belts the flexibility to bend around small-diameter pulleys.

Banded V-Belts

Also known as serpentine belts, these have multiple bands that function as a single unit for consistent drive performance and even load distribution. They handle shock loads better than standard belts.

Double V-Belts

Grooves on both sides of these belts transmit equal power, making them ideal for serpentine drives.

Adjustable-Length V-Belting

Twist-Lock Adjustable-Length V-Belting

Twist the tabbed links together to form a belt. Because it’s made of individual links, this belting allows you to change your belt length without dismantling your drive.

Grip-Top Twist-Lock Adjustable-Length V-Belting

Install these belts without dismantling your drive shafts—hook the ends together with the attached stainless steel connector.

Heavy Duty Made-to-Order Round Belts

These belts are reinforced with a polyester cord for strength.

Chemical-Resistant Made-to-Order Round Belts

In addition to chemical resistance, these belts also provide increased abrasion resistance over heavy duty round belts.

Quick-Connect Hollow-Core Round Belting

The hollow core of this polyurethane belting allows you to join the ends without trimming, welding, or using special tools.

Adjustable-Length Round Belting

Lengthen or shorten this polyurethane belting without tools or connectors—the interlocking links attach and detach with a twist.

Ultra-Flexible Round Belting

Coiled-metal construction provides flexibility to bend around small-diameter pulleys and accommodate curved belt drives and misaligned pulleys.
