    CSK20 Sprag Clutch One Way Bearing can be used as freewheels and can be used in backstop, overrunning or indexing applications. Freewheel bearings are characterized by their ability to turn in one direction only and thus transmit torque whilst having a zero backlash. They are supplied filled with grease and are low maintenance. The torque is transmitted on the inner and outer race by an external key way to the housing and onto the shaft by an internal key way.
