One-Way Locking Ball Bearing Clutches

Shielded

Sealed
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.
