Description
Type CSK or KK is a sprag type freewheel intefrated into a 62 series ball bearings (execpt sizes 8 and 40). It is bearings supported, delivered grease lubricated and protected against dust of more then 0.3mm. The use of addotional :nylos" type seals os recommended especially when the working temperature exceeds 50C.
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 N6 tolerance and onto a shaft with n6 tolerance. 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, prefirmance will be reduced or a C3 bearing clearance will be necessary.
Operating Temperature range : -40C to + 100C. Packs upto +120C are acceptable for short periods.
CSK or KK 2RS is 5 mm wider but is equiped with lip seals to be water splash resistant.
