Finished Sprockets | McMaster-Carr

Often used in electronic equipment, instrumentation devices, printers, and other compact machinery, these sprockets are made for use with our miniature roller chain.

Idler Sprockets

Idler Sprockets for ANSI Roller Chain

These sprockets are made of steel.

Wear-Resistant Idler Sprockets for ANSI Roller Chain

Hardened teeth give these steel sprockets increased wear resistance for a long service life.

Lightweight Idler Sprockets for ANSI Roller Chain

Made of nylon, these sprockets are lightweight, quiet, and corrosion resistant.

Wear-Resistant Wide-Hub Idler
Sprockets for ANSI Roller Chain

Hardened teeth give these steel sprockets increased wear resistance for a long service life.

Wide-Hub Idler Sprockets for ANSI Roller Chain

A wide hub provides these sprockets with stability under heavy loads.

Idler Sprockets for Metric Roller Chain

Keep constant tension on your drive with these sprockets that press against your metric ISO roller chain to take up slack and reduce wear and vibration.

Idler Sprockets for Double-Strand ANSI Roller Chain

These idler sprockets have two rows of teeth for use with double-strand ANSI roller chain.

Timing Belts and Pulleys

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.

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.

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.

XL Series Timing Belt Pulleys

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

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.

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.

High-Strength Timing Belts and Pulleys

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 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 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.

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.

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.
