The main peculiarity of the angular contact ball bearing consists in the slightly different positions of the internal and external bearing raceways (they do not share the same axle). This particular configuration is typically advised for combined loads when radial and axial loads act at the same time. The double row angular contact ball bearing can be seen as two angular contact ball bearings with an O-configuration setup or an X-configuration setup. It can support radial and axial loads with an axial load from both sides. It is narrower than a couple of angular contact ball bearings.
