Timing Belts and Pulleys

XL Series Corrosion-Resistant Timing Belt Pulleys

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

XL Series Lightweight Timing Belt Pulleys

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

L Series Corrosion-Resistant Timing Belt Pulleys

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

MXL Series Corrosion-Resistant Timing Belt Pulleys

Anodized aluminum has good corrosion resistance.

MXL Series Lightweight Timing Belt Pulleys

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

MXL Series Timing Belts

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

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.

Timing Belt Idler Pulleys

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

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.

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.

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.

High-Strength Ultra-Quiet Timing Belts

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

High-Strength Ultra-Quiet Timing Belt Pulleys

Teeth are curved and set in an offset pattern for high strength with 25% less operating noise than pulleys and belts with trapezoidal teeth.

V-Belts and Pulleys

Taper-Lock Bushing-Bore V-Belt Pulleys

Mount these pulleys with a taper-lock bushing for a tight, wobble-free hold on your shaft.

V-Belts

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

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.

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.

Press-Lock Adjustable-Length V-Belting

Steel rivets hold the individual links together. Use an installation tool to add or remove links.

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.

Round Belts

Made of polyurethane, these belts resist chemicals and abrasion.

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.

Chemical-Resistant Made-to-Order Round Belts

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

Textured Round Belting

The textured surface improves gripping ability.

Round Belting

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

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.

Bushings for Bushing-Bore Sprockets and Pulleys

Quick-Disconnect (QD) Bushings

The screw connections on these bushings easily mate to compatible quick-disconnect sprockets and pulleys.

Split-Tapered Bushings

The tapered barrel on these bushings is split on both sides, allowing them to contract more tightly around the shaft than quick-disconnect and taper-lock bushings.

Taper-Lock Bushings

Mount these hubless bushings flush into your sprocket or pulley for a slim profile with no protruding screws.

Hex Flanged Eccentric Bushings

Often used with V-groove wheels or track roller carriages, these off-center bushings create precise mounting clearance.

Bushings for Sprockets and Pulleys

Quick-Grip Screw-Clamp Bushings

Also known as Trantorque bushings, these tighten with a twist of the collar nut—no screws needed.

Flanged Screw-Clamp Bushings

A mounting flange prevents movement during tightening.

Flush-Mount Screw-Clamp Bushings

Insert these bushings into the bore of your sprocket for flush or recessed mounting.

Corrosion-Resistant Flanged Screw-Clamp Bushings

Made from stainless steel or plated with nickel, these bushings resist corrosion. A mounting flange prevents movement during tightening.

Corrosion-Resistant Flush-Mount
Screw-Clamp Bushings

Insert these nickel-plated steel bushings into the bore of your sprocket for flush or recessed mounting in wet environments.

Quick-Grip Flanged Hydraulic Bushings

Tighten just one set screw to clamp these bushings evenly around your shaft. The screw forces hydraulic fluid in between the double-walled sleeve, expanding the two walls against the shaft and the hub of your sprocket, pulley, or gear for a tight hold.
