A Bearing arrangement for a wind turbine generator having a stator and a rotor is provided. The bearing arrangement comprises a first, a second and a third roller unit group (110,112,114) each comprising multiple roller units (108) for rotatably supporting the rotor with respect to said stator. The roller units are circularly arranged around a bearing arrangement axis. Furthermore, each roller unit comprises a single roller and is individually replaceable. In the bearing arrangement, the roller units of the first and second roller unit group are arranged with their longitudinal axes extending substantially perpendicular with respect to the bearing arrangement axis. The roller units of the third roller unit group are arranged with their longitudinal axes extending substantially parallel with said bearing arrangement axis. The bearing arrangement further comprises a rotor ring and the roller units are arranged in rolling contact with the rotor ring. |
