Indexing Overrunning Starter Clutch One Way Bearing CSK20PP With Keyway

Sprag Clutches Overrunning Indexing Backstopping Bearing With Keyway CSK20PP

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.

CSK..P

CSK..P has the same construction and outside dimensions as type CSK, but has a keyway on the inner race. These clutches can be mounted on a shaft with recommended k6 tolerance and the outer race must be pressed into a rigid housing with a recommended N6 tolerance. The resulting housing and shaft diameters must be checked to ensure that the bearing has adequate radial clearances.

CSK..PP

CSK..PP features a keyway on both the inner and outer race. The recommended mounting tolerances are k6 on the shaft and K6 in the rigid housing. A h6 tolerance on the shaft or H6 in the housing are also acceptable for a light press fit assembly. Always check to ensure that the bearing has adequate radial clearances. Operating temperature: 21 to 140°F (-6 to 60°C). Special greases are available for operating temperatures: -40 to 212°F (-40 to 100°C

Typical Mounting Arrangement

The Model CSK..P clutches must be secured to the shaft by customer supplied snap ring, set collar, spacer, etc. The outer race is secured with a press fit to a N6 tolerance. The Model CSK..PP clutches have a keyseat on both races and must be secured by customer supplied snap ring, set collar, spacer, etc.
