The spiral teeth on these bevel gears stay in contact longer than straight teeth, so they can handle heavier loads at higher speeds. Use them to transmit motion at a right angle while changing shaft speed and torque. Their teeth engage gradually, which reduces vibration and noise, and they’re hardened for extra wear resistance. All are carbon steel for good strength. They have a machinable bore, so you can customize the size within the For Shaft Diameter range listed.

A complete set consists of a large gear and a small gear, also known as a pinion (sold separately). For the gears to mesh correctly, they must have the same face width, pitch or module, and pressure angle.
