One Way Clutch Overrunning Indexing Backstopping Bearing Sprag Clutches CSK20
CSK
Type CSK is a sprag type clutch integrated into a 62 Series ball bearing (except sizes 8 and 40).
It is bearing supported, shipped grease lubricated and protected against dust larger than .012” (.3mm) diameter. The use of additional “nylos” type seals is recommended especially when the working temperature exceeds 122°F (50°C).
Oil bath lubrication is also possible if the original grease is first flushed out using a suitable solvent.
Torque transmission is ensured by a press fit assembly into a rigid outer housing with a recommended N6 tolerance and onto a shaft with a recommended n6 tolerance. The resulting housing and shaft diameters must be checked to ensure that the bearing has adequate radial clearances.
The initial bearing radial clearance is set at C5, and is reduced if using the press fit as specified.
One race may be glued. If both races are to be glued, performance will be reduced or a C3 bearing clearance will be necessary.
Operating temperature: 21 to 140°F (-6 to 60°C).
Special grease available for operating temperatures: -40 to 212°F (-40 to 100°C)
CSK..2RS
CSK..2RS clutches are .197” (5mm) wider than a standard 62 Series bearing, as they are equipped with lip seals for washdown applications.
