Abstract
A spherical roller bearing having an outer ring providing at least one inner raceway, an inner ring providing a first and a second outer raceway, a plurality of roller elements arranged in a first and second roller row in-between the at least one inner raceway and the respective first and second outer raceway is provided. The bearing provides a cage for guiding the roller elements in the first and second roller row, the cage includes a plurality of cage pockets, wherein in each cage pocket one of the roller elements is disposed. The bearing further presents a specific pitch circle diameter (PCD), and the cage is essentially in-pitch roller centered in relation to the pitch circle diameter (PCD) when there is an axial force acting on the bearing. In addition, the present invention regards a bearing arrangement and a wind turbine bearing arrangement.
