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.

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 sprockets, these have a slim profile that fits in narrow spaces.

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.

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.

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

Use these sprockets with compatible QD bushings.

Taper-Lock Bushing-Bore
Sprockets for ANSI Roller Chain

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

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.

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.

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 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.

Timing Belt Idler Pulleys

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

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.

Metal Gears and Gear Racks

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 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.

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.

Metal Worms and Worm Gears

Worm gears use screw threads to reduce shaft speed by ratios of 10:1 and greater while transmitting motion at a right angle.

Metal Bevel Gears

A type of miter gear where one gear is smaller than the other, bevel gears provide right-angle speed reduction at ratios ranging from 2:1 to 5:1. They’re more efficient than worm gears because they create less friction.

Plastic Gears and Gear Racks

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

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

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.

Plastic Worm Gears

These plastic gears are lighter and quieter than metal gears—pair them with metal worms for lubrication-free operation. Worm gears use screw threads to make large reductions to shaft speed while transmitting motion at a right angle.

Plastic Miter Gears

Connect two shafts at a right angle without changing shaft speed or torque.

Ratcheting Gears

Metal Ratcheting Gears

Compared to plastic gears, metal gears are better for high-load, high-speed, and heavy duty applications.

Plastic Ratcheting Gears

A light duty alternative to metal, plastic gears have good corrosion and chemical resistance.
