About Roller Chain and Sprockets

Sprockets for ANSI Roller Chain

Mount these sprockets onto your shaft and secure with a set screw—no machining necessary.

Wear-Resistant Sprockets for ANSI Roller Chain

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

Corrosion-Resistant Sprockets for ANSI Roller Chain

Mount these sprockets onto your shaft and secure with a set screw—no machining necessary.

Sprockets for Metric Roller Chain

Designed to meet ISO 606 and DIN 8187 international dimensional standards, these sprockets are for use with compatible ISO and DIN roller chain.

Flat Sprockets for Metric Roller Chain

With metric teeth and slim profile, these sprockets allow your ISO roller chain to reach narrow spaces. They're commonly referred to as A-plate sprockets.

Sprockets for Double-Strand Metric Roller Chain

The double row of teeth on these sprockets are designed to fit into metric ISO double-strand roller chain.

Quick-Disconnect (QD) Bushing-Bore
Sprockets for ANSI Roller Chain

Use these sprockets with compatible QD bushings.

Split-Tapered Bushing-Bore
Sprockets for ANSI Roller Chain

Since these sprockets grip bushings more tightly than taper-lock sprockets, they’re often used in high-torque applications.

Taper-Lock Bushing-Bore
Sprockets for Metric Roller Chain

While their teeth fit into metric ISO roller chain, these sprockets use taper-lock bushings to grip shafts.

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.

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.

MXL Series Lightweight Timing Belt Pulleys

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

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 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.

Gears and Gear Racks

Metal Gears and Gear Racks—20° Pressure Angle

The current industry standard, these 20° pressure angle gears have thicker, stronger teeth than 14½° pressure angle gears. They're also known as spur gears.

High-Power Metal Gears

For smooth, quiet operation at high speeds under heavy loads, helical gears have curved teeth that engage gradually and stay in contact longer than straight teeth.

Plastic Gears and Gear Racks—20° Pressure Angle

The current industry standard, gears with a 20° pressure angle have thicker, stronger teeth than gears with a 14½° pressure angle.
