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

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.

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 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.

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 Cut-to-Length Timing Belts

Designed for use in linear motion drives, these belts are neoprene with fiberglass reinforcement for quiet operation with high strength.

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.

T Series Timing Belt Pulleys

Made of aluminum, these pulleys have good corrosion 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.

AT Series Timing Belt Pulleys

Made of aluminum, these pulleys have good corrosion 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.

Timing Belt Idler Pulleys

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

XH Series Quick-Disconnect Timing Belt Pulleys

Securely carry heavy loads—these pulleys mount with a bushing for a better grip on the shaft than set screws and press-fit pulleys.

XH Series Timing Belt Pulleys

Made of iron, these pulleys are strong enough to carry extra heavy loads.

XH Series Timing Belts

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

XXH Series Quick-Disconnect Timing Belt Pulleys

To prevent slippage while moving extra heavy loads, these pulleys mount with a bushing for a more secure grip on the shaft than set screws and press-fit pulleys.

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 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 Pulleys

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

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 with Hex Bore

Mount these high torque drive (HTD) pulleys onto a hex shaft.

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 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.

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.
