Timing Belts and Pulleys

XL Series Corrosion-Resistant Timing Belt Pulleys

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

XL Series Timing Belt Pulleys

Pulleys are XL series (extra light) and have trapezoidal teeth.

XL Series Lightweight Timing Belt Pulleys

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

L Series Quick-Disconnect Timing Belt Pulleys

Carry heavy loads without slippage—pulleys mount with a bushing for a more secure grip on the shaft than set screws.

L Series Timing Belt Pulleys

These L series (light) pulleys and have trapezoidal teeth.

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.

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.

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.

T Series Timing Belt Pulleys

Made of aluminum, these pulleys have good corrosion resistance.

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.

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.

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 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

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

High-Strength HTD Timing
Belt Pulleys with Hex Bore

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

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.
