Width tolerance: +/-0.05mm, Depth tolerance: 0/+0.1mm
Type CSK is a sprag type clutch integrated into a 62 Series ball bearing(except size 8 and 40). It is bearing supported, shipped greae lubricated and protected against dust larger than 0.3mm diameter. The use of additional "nylos" type seals is recommended especially when the working temperature exceeds 122F (50C).
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,performance will be reduced or a C3 bearing clearance will be necessary. Operating temperature range: -4F(-20C) to 212F(+100C). Peaks up to 248F(+120C) are acceptable for short periods.
The type CSK clutches must be mounted with a press fit on both the outer and inner races. The shaft diameter tolerance must be held to a n6. The bore of the housing for the outer race should be a N6 tolerance.
CSK-2RS clutches are 5mm wider than a standard 62 series bearing, as they are equipped with lip seals for washdown applications.
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 to k6 tolerance. The outer race must 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 k6 on the shaft and K6 in a rigid housing. An h6 tolerance on the shaft or H6 in the housing are also acceptable for a light press fit assembly.
