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.
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.
