High-Load Metal Spiral Bevel Gears
 |
Gears Sold Separately |
 |
Large Gears |
 |
Small Gears |
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.
Speed Ratio—The ratio by which shaft speed is reduced when transferring motion from the smaller to the larger gear. To increase shaft speed, transfer motion from the larger to the smaller gear. Changing shaft speed also changes torque: as speed decreases, torque increases. To achieve the speed ratio listed, match it across a set of compatible gears.

High-Power Metal Miter Gears
 |
Keyed Bore with Set Screw |
 |
 |
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.
