RKB double row angular contact ball bearings can be considered in design similar to a pair of single row angular contact ball bearings in O or X configuration. They can accommodate thrust loads as well as high radial loads. These bearings are normally used in arrangements requiring a rigid axial guidance and they can also withstand tilting moments.
