The primary task of a gear is to mesh teeth with another toothed part to transmit torque or to translate rotation. Thus, geared devices can change the speed, torque, and direction of a power source. When two gears of unequal number of teeth combine, it results in a mechanical advantage, with both the rotational speeds and the torques of the two gears differing in a simple relationship.

A number of devices use gears in some mechanical arrangement and these devices go by a number of names, depending on the branding of the manufacturer. We offer an extensive array of gearing products, including Gearboxes, Gearheads, and Gear Reducers
