About Roller Chain and Sprockets

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 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 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 Ratcheting Gears

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

Gear Tooth Pitch Identifiers

When replacing a gear, use these gauges to identify pressure angle, pitch, and module.

Chain and Belt Drives

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.

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.

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.

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.
