Four-Point Contact Ball Bearings


Four-point contact ball bearings have a single outer ring and a split inner ring. The raceway profiles are such that the ball contacts the outer ring at two points and the split inner ring at one point each. Such a design allows the bearing to carry axial loads in both the directions like a double row angular contact ball bearings without taking up as much axial space. These bearings can support light radial loads.
