About Sizing Belts

Made-to-Order Flat Belts

These oil-resistant Buna-N belts have a nylon core.

Abrasion-Resistant Made-to-Order Flat Belts

Made of polyurethane, these belts are chemical and abrasion resistant.

Flat Belting

Weld the ends of this belting together for a firm hold.

Round Belts

Made of polyurethane, these belts resist chemicals and abrasion.

Flexible Round Belts

These neoprene belts are more flexible than polyurethane belts.

Textured Round Belts

Often used with lathes and conveyors, these textured belts grip loads better than standard round belts, making sure heavy loads don’t slip.

Static-Control Round Belts

Made of a specially formulated polyurethane, these belts prevent the static buildup that could damage sensitive equipment in your setup.

Low-Temperature Round Belts

Made of hytrel polyester, these belts can be used in lower temperatures than standard polyurethane belts without becoming brittle.

Chemical-Resistant Made-to-Order Round Belts

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

Heavy Duty Made-to-Order Round Belts

These belts are reinforced with a polyester cord for strength.

Quick-Hook Twisted Round Belts

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

Textured Round Belting

The textured surface improves gripping ability.

Round Belting

This belting has a smooth, easy-to-clean surface.

Heavy Duty Round Belting

This polyurethane belting is reinforced with a polyester cord for strength.

Timing Belts and Pulleys

MXL Series Cut-to-Length Timing Belts

Used to drive small-scale linear motion applications, these belts are neoprene with fiberglass reinforcement for quiet operation with high strength.

MXL Series Timing Belts

Quiet-running neoprene is reinforced with high-strength fiberglass for use in general purpose drive systems.

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.

XL Series Dust-Free Timing Belts

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

XL Series Heat-Resistant Timing Belts

Resisting temperatures up to 400° F, silicone can take the heat. Belts have Kevlar reinforcement, which has very high strength, low stretch, and excellent shock resistance.

XL Series Timing Belts

Belts combine neoprene with fiberglass reinforcement for quiet operation with high strength.

XL Series Timing Belts with Teeth on Both Sides

Often used in reversing and serpentine drive systems, teeth on both sides allow you to rotate pulleys in opposite directions. Belts are quiet-running neoprene and high-strength fiberglass.

H Series Timing Belts

Good for use in general purpose drive systems, these belts combine quiet-running neoprene with high-strength fiberglass reinforcement.

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 Heat-Resistant Timing Belts

Enduring temperatures up to 400° F, silicone is the best choice for use in hot environments. Belts 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.

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.

L Series Dust-Free Timing Belts

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

L Series Timing Belts

Neoprene is reinforced with fiberglass for quiet operation with high strength.

L Series Heat-Resistant Timing Belts

Withstanding temperatures up to 400° F, silicone is the best choice for use in hot environments. Belts have Kevlar reinforcement, which has very high strength, low stretch, and excellent shock resistance.

L Series Timing Belts with Teeth on Both Sides

Use a single belt to drive three or more pulleys in reversing and serpentine drive systems. These belts have teeth on both sides to transmit power from either side and rotate pulleys in opposite directions. Belts are neoprene with fiberglass reinforcement for quiet operation with high strength.

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 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

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.

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.

Ultra-Flexible Banded V-Belts

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

Precision-Matched V-Belts

Ensure even load distribution on drives with multiple belts.

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.

Double V-Belts

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

Profile-Top V-Belting

A range of specially shaped tops carry materials in conveying applications.

Banded V-Belting

Bands provide extra surface contact for handling high speed ratios.

V-Belting

Made of chemical- and abrasion-resistant polyurethane rubber, this belting is often used in light to medium duty power-transmission and conveying applications.

Belts for Vacuum Cleaners

Replace belts in common upright vacuum brands.

V-Belts for V-Groove Conveyor Rollers

Replace worn and broken V-belts on conveyor rollers.
