One Way Clutch Bearings
Internal locking elements (sprags) lock to transmit torque in one direction while turning freely in the other direction. Use them in applications where precision movement is required, such as pick-and-place and automated indexing conveyor systems. Shields keep out dust and contaminants.
Shielded bearings dissipate heat better than sealed bearings, but don’t keep out as much dust.
For dirty or dusty environments, sealed bearings are the best choice, since they block out contaminants better than shielded bearings.

It resembles a roller bearing, but instead of cylindrical rollers, non-revolving asymmetric figure-eight shaped sprags are used. When the unit rotates in one direction the rollers slip or free-wheel, but when a torque is applied in the opposite direction, the rollers tilt slightly, producing a wedging action and binding because of friction.
The scope of applications for one-way clutches covers a wide spectrum from small office machines to heavy machinery and long conveyors.
