These bearings provide a solution for applications were hardened and ground raceways are provided on the shaft or in the housing bore. Because RNU design bearings, for example, do not need an inner ring, the bearing arrangement design can be downsized or the shaft diameter can be larger to provide a stronger, stiffer arrangement. Additionally, the possible axial displacement of the shaft relative to the housing is only limited by the width of the raceway on the shaft for the RNU design or in the housing bore for the RN design.
