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 hardened teeth are more wear resistant than gears with teeth that are not hardened. Gears with teeth that are not hardened can be hardened to fit your application. Hardening a gear's teeth increases its wear resistance.

Metal Miter Gears
With straight, conically shaped teeth and a 1:1 speed ratio, miter gears connect two shafts at an angle without changing shaft speed or torque. They're more efficient than spiral miter gears because they create less friction.
For two gears to mesh correctly, they must have the same pressure angle, shaft angle, pitch/module, and number of teeth.
Carbon steel gears have hard, strong, and wear-resistant teeth. They’re best for heavy duty and high-torque applications, such as lifting equipment. However, these gears will rust when exposed to moisture or corrosive chemicals. Some gears have hardened teeth for additional wear resistance; gears with teeth that are not hardened can be hardened to fit your application.

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.
Bronze gears have low friction and dissipate heat better than cast iron gears to provide a long service life for both the gear and the worm. They’re also more corrosion resistant than cast iron gears.

High-Power Metal Miter Gears
Also known as spiral miter gears, these gears have curved teeth that stay in contact longer than straight teeth so they handle heavier loads at higher speeds. They run quieter than standard miter gears because the teeth gradually engage. Use them to transmit motion at a right angle while maintaining shaft speed and torque. Gears are carbon steel for strength. Teeth are hardened for wear resistance.
Gears must be identical in order to mesh correctly; they're sold as a pair.
