Claim:
1. A spherical roller bearing, comprising, an outer ring including at least one inner raceway, an inner ring including a first and a second outer raceway, a plurality of roller elements arranged in a first and second roller row disposed between the at least one inner raceway and the first and second outer raceway, when an axial force is applied to the spherical roller bearing one of the first and second roller rows becomes a loaded row and the other one of the first and second roller rows becomes an unloaded row, the first roller row having a first rotational axis and the second roller row having a second rotational axis wherein the first and second rotational axes of the first and second roller rows, respectively, can vary upon shaft displacement, a cage for at least one of guiding and retaining the roller elements in the first and second roller row, the cage having a plurality of cage pockets, wherein one the roller elements is positioned in each of the plurality of cage pockets, the cage is not able to prevent the plurality of roller elements from falling out of the cage in an axial direction, the bearing further presents a specific pitch circle diameter (PCD), and wherein when the axial force is applied to the spherical roller bearing the cage is configured to center on the loaded row such that upon variation of the first and second rotational axes due to shaft displacement the cage will center on a loaded row rotational axis.
