Spur & Change Gears

Discover a wide array of shaft couplings, chains and sprockets, belts and sheaves, and drive components.
Spur and change gears transmit torque from one shaft to another. Spur gears are round with external teeth. They are mounted on parallel shafts and used in interlocking pairs. A motor rotates the shaft of the smaller spur gear, which then rotates the larger spur gear and the driven shaft. Change gears adjust speeds and transfer torque. They are mounted on bushings that fasten onto shafts. Change gears are typically used in applications where the gear ratio changes frequently.
