The axial minimum load is necessary, because we must to ensure the low friction at high speeds. Addition to that, to ensure the bearings can accommodate the higher axial loads, four-point contact ball bearings have a split inner ring, this enables a large number of balls to be incorporated in the bearings.

SKF bearings company provide the QJ design four-point contact ball bearings have a contact angle of either 35 degree or 45 degree, the outer ring with cage assembly and ball can be mounted separately from the two inner ring halves.
