NOVELTY - The bearing assembly (1) has a toroidal roller bearing arrangement (20) that comprises a first set of rolling elements (21). The inner and outer raceways (24,26) are arranged to allow for axial and angular displacement between the inner and outer rings (23,25). A second set of rolling elements (31) are arranged to cooperate with a second inner raceway (34) and a second outer raceway (36) for supporting axial loads and for restricting axial movement of a shaft (2) in relation to the first outer ring of the rolling elements.    USE - Bearing assembly for supporting shaft of wind turbine arrangement (claimed). Can also be used in gear box, propeller/impeller/turbine shafts, hub units such as wheel or rotational hub units, process applications, construction applications, construction vehicle solutions, drive train applications, actuator applications comprising rotatable shafts.    ADVANTAGE - The structure of the bearing assembly is simplified. The installation space, weight and production cost of the bearing assembly are reduced. The performance of the bearing assembly is improved. The rotational inertia of the bearing assembly is decreased allowing for more efficient operation. The internal loads are lowered to reduce the friction of the bearing assembly which leads to reduced power loss. The limitation of axial displacement of the rotating shaft during operation is improved which increases life time of the bearing assembly and performance of devices operatively connected to the rotating shaft.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following:    (1) a wind turbine arrangement; and    (2) a method for manufacturing a bearing assembly for supporting a shaft.
