Abstract
An angular contact toroidal rolling element bearing includes an inner ring, an outer ring, a set of rollers arranged between the inner and outer rings, and a cage having a plurality of pockets, each pocket retaining one of the rollers. Each roller has a curved raceway-contacting surface arranged for being in load carrying contact with a curved inner raceway of the inner ring and in load carrying contact with a curved outer raceway of the outer ring. A contact angle between each roller and the inner and/or outer raceway is inclined, and each roller is arranged to self-orient in its axial direction in relation to the inner and outer rings in a loaded zone during operation of the bearing. At least one of the pockets present an inclination angle in relation to an orbital trajectory of rotation of the rolling elements during operation of the bearing.
