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.

High-Power Metal Bevel Gears
Made from carbon steel with spiral teeth, these gears handle heavier loads at higher speeds than bevel gears with straight teeth because their teeth stay in contact longer. Their teeth engage gradually, which reduces vibration and noise, and they’re hardened for extra wear resistance. Use these gears to transmit motion at a right angle while changing shaft speed and torque. They reduce speeds at ratios of 2:1, 3:1, or 4:1. Customize their machinable bore to fit them on a variety of shafts. They’re also known as spiral bevel gears.
A complete set consists of a gear and pinion (sold separately). The gear is larger than the pinion, but for them to mesh correctly, they must have the same pressure angle, 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.
