CSK Series (One-Way Bearing) The CSK model freewheel is a sprag type clutch integrated into a 6200 series ball bearing (except sizes 8 and 40). It provides you with a one way clutch, and eliminates the need for a ball bearing. It gives a high degree of freewheeling accuracy while utilizing a minimum of space. 
The CSK model freewheels can be used in backstop, overrunning or indexing applications. 
For SPINNING REELS (fishing baitrunner Reels/Fishing Reels), The tension of the free spool can be controlled with an easy to reach rear adjustment. Nine stainless steel , sealed bearing and a one-way clutch bearing make these reels smooth. 
CSK series one way (direction) bearing consists of a standard ball bearing, in-built special snap block and cage, widely used in washing machine, hydraulic machinery, printing machines, textile machinery and so on.
