Wear-Resistant Wide-Hub Idler Sprockets for ANSI Roller Chain
Hardened teeth give these steel sprockets increased wear resistance for a long service life. The wide hub provides stability under heavy loads. Designed to rotate freely on built-in bearings, idler sprockets maintain constant tension on your drive by pressing against your chain to take up slack and reduce wear and vibration. They are for use with roller chain tensioners.

Metal Gears and Gear Racks—14 1/2° Pressure Angle
A former industry standard, 14½° pressure angle gears are often found on older machinery. Made of carbon steel, they have high strength and are better than plastic gears and gear racks for high-load, high-speed, and heavy duty applications.
Combine gears with different numbers of teeth to change speed and torque in your assembly. Combine a gear and rack to convert rotary motion into linear motion.
For components to mesh correctly, they must have the same pressure angle and pitch.
Gears with machinable bore have a large hub diameter so you can machine them to fit your shaft.
Gears with teeth that are not hardened can be hardened to fit your application. Hardening a gear's teeth increases its wear resistance.

Metal Worms and Worm Gears
Worm gears use screw threads to make large reductions to shaft speed while transmitting motion at a right angle. They transmit motion from worm to gear and cannot be reversed. For gears and worms to mesh correctly, they must have the same pressure angle and pitch/module. These worms are compatible with plastic worm gears.
Speed ratio is the ratio by which output shaft speed is reduced. As speed decreases, torque increases.
Cast iron gears are strong and durable.

Metal Bevel Gears
A type of miter gear where one gear (sometimes called a pinion) is smaller than the other, bevel gears provide right-angle speed reduction at speed ratios ranging from 2:1 to 5:1. All are carbon steel for strength; they're compatible with plastic bevel gears. Teeth are not hardened so you can harden them to fit your application. Hardening a gear’s teeth increases its wear resistance.
A complete set consists of a gear and pinion (sold separately). For a gear and pinion to mesh correctly, they must have the same pressure angle, pitch/module, and face width. Speed ratio is the ratio by which shaft speed is reduced when transferring motion from pinion to gear. To increase shaft speed, transfer motion from gear to pinion. Changing shaft speed also changes torque: as speed decreases, torque increases.
