One Way Bearing

About One Way Bearing

A one-way bearing, also known as a clutch bearing or overrunning clutch, is a specialized bearing that allows rotation in only one direction while preventing movement in the opposite direction. It uses precision rollers or sprags that lock when reversed, creating a secure, non-slip hold. When rotated in the permitted direction, the bearing spins freely with minimal friction. One-way bearings are commonly used in applications requiring controlled directional motion, such as conveyor systems, starter motors, backstopping devices, fitness equipment, and indexing mechanisms. Their compact design, reliability, and automatic engagement make them ideal for preventing reverse rotation and ensuring smooth, efficient operation.
