The CSK Series is a sprag type clutch integrated into a 62 Series ball bearing (except sizes 8 and 40).
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 with recommended k6 tolerance and the outer race must be pressed into a rigid housing with a recommended N6 tolerance . The resulting housing and shaft diameters must be checked to ensure that the bearing has adequate radial clearances .
CSK . .PP features a keyway on both the inner and outer race . The recommended mounting tolerances are k6 on the shaft and K6 in the rigid housing . A h6 tolerance on the shaft or H6 in the housing are also acceptable for a light press fit assembly . Always check to ensure that the bearing has adequate radial clearances.
CSK . .2RS clutches are .197” (5mm) wider than a standard 62 Series bearing, as they are equipped with lip seals for washdown applications .
