A double-row angular contact ball bearing is basically two single-row angular contact ball bearings with 20 deg contact angles, mounted back-to-back while contained within a narrower single bearing. These bearings occupy less axial space and can take a bi-directional axial, radial and moment loads in one bearing where it takes a matched pair otherwise. More economical than two matched single-row angular contact bearings. Single bearing yields handling and mounting benefits. More compact than two single-row bearings. Support radial and axial loads in either direction. Capable of some moment load. Sealed bearings are maintenance-free. Low noise. Energy efficient. Cost effective. Reduced friction. Long life.
