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.

Machinable-Bore Sprockets for ANSI Roller Chain

For a custom fit on your shaft, these sprockets can be machined to your exact specifications.

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.

Machinable-Bore Corrosion-Resistant
Sprockets for ANSI Roller Chain

For a custom fit on your shaft, these sprockets can be machined to your exact specifications.

Lightweight Sprockets for ANSI Roller Chain

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

Flat Sprockets for ANSI Roller Chain

Also known as A-plate and weld sprockets, these have a slim profile that fits in narrow spaces and are often welded directly to a shaft.

Sprockets for Double-Strand ANSI Roller Chain

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

Sprockets for Two Single-Strand ANSI Roller Chains

Reduce assembly time when setting up a system to drive two different roller chains from a single sprocket.

Sprockets for Triple-Strand ANSI Roller Chain

Three rows of teeth make these sprockets compatible with triple-strand ANSI roller chain.

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.

Machinable-Bore Corrosion-Resistant
Sprockets for Metric Roller Chain

Machine the center of these sprockets to fit the exact dimensions of your shaft. The teeth are sized to fit into metric ISO 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.

Sprockets for Miniature Roller Chain

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

Sprockets for Harsh Environment Flat-Edge Roller Chain

Sprockets for Harsh Environment
Flat-Edge Roller Chain

The teeth on these sprockets are sized to fit Harsh Environment Flat-Edge Roller Chain.

One-Way Sprockets

Transfer power in one direction with these sprockets, which spin freely in the opposite direction.

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.

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.

Bushing-Bore Sprockets

Taper-Lock Bushing-Bore
Sprockets for ANSI Roller Chain

Get the same sizing versatility as quick-disconnect sprockets while using less space.

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

Use these sprockets with compatible QD bushings.

Taper-Lock Bushing-Bore Sprockets
for Double-Strand ANSI Roller Chain

Switch out the bushing to install these sprockets on shafts with different diameters—no machining necessary.

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 Corrosion-Resistant Timing Belt Pulleys

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

L Series Timing Belt Pulleys

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

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.

MXL Series Lightweight Timing Belt Pulleys

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

MXL Series Corrosion-Resistant Timing Belt Pulleys

Anodized aluminum has good corrosion resistance.

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.

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.

Metal Gears and Gear Racks—
14 1/2° Pressure Angle

A former industry standard, 14½° pressure angle gears are often found on older machinery.

Metal Miter Gears

With straight, conically shaped teeth and a 1:1 speed ratio, miter gears connect two shafts at a right angle without changing shaft speed or torque. They're more efficient than spiral miter gears because they create less friction.

High-Power Metal Miter Gears

Also known as spiral miter gears, these gears have curved teeth that gradually engage and stay in contact longer than straight teeth so they handle heavier loads at higher speeds. Speed ratio is 1:1.

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.
