Double row angular contact ball bearings, with wide and split inner ring, correspond to a pair of single row angular contact ball bearings in a back-to-back arrangement, while requiring less axial space. Because of the split inner ring, they incorporate a larger number of balls, and have a larger contact angle, giving the bearings a high load carrying capacity, especially in the axial direction.
