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.
