One Way Clutch Bearing CSK Series
Type CSK is a sprag type freewheel integrated into a 62 series ball bearing (except sizes 8 and 40). It is bearing supported, delivered grease lubricated and protected against dust of more than 0, 3 mm. The use of additional "nylos" type seals is recommended especially when the working temperature exceeds 50° C. Oil bath lubrication is also possible.
All the CSK versions are equipped with "formchromed" sprags. This process increases several times the overrunning life time. 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.
Please contact us when either the ambient or the operating temperature is not within the range +5° C to +60° C. CSK...2RS is 5 mm wider but is equiped with lip seals to be water splash resistant.
Types CSK...P and CSK...PP are sprag type freewheels integrated into 62...Series ball bearings (except size 40). They are bearing supported, delivered grease lubricated and protected against dust of more than 0, 3 mm.
The use of additional "nylos" type seals is recommended especially when the working temperature exceeds 50° C. Oil bath lubrication is also possible.
In addition to the basic CSK model, type CSK...P features a keyway on the inner race. For this reason it can be keyed to a shaft to k6 tolerance. The outer race must still be pressed into a rigid housing to N6 tolerance.
CSK...PP features a keyway on both the inner and outer race. The recommended mounting tolerances are h6 on the shaft and H6 in a rigid housing. Please contact us when either the ambient or the operating temperature is not within the range +5° C to +60° C.
