A bearing assembly having an axially extending axis of rotation, comprising: an inner ring; an outer ring including an outer radial surface, an inner radial surface, and a raceway disposed in the inner radial surface, the raceway defined by a first surface and a second surface, and the first surface intersects with the second surface at a point aft of an axial midpoint of the raceway the outer ring including a plurality of apertures that provide a fluid passage between the raceway and an exterior surface of the outer ring, a first end of each of the plurality of apertures substantially aligned with the intersection of the first surface and the second surface; and a plurality of bearing elements disposed between the inner ring and the outer ring the assembly; wherein the first surface has a parti-circular shape with a first radius and a first origin, and the second surface has a parti-circular shape with a second radius and a second origin, and the first origin and second origin are displaced from one another; characterised in that the length of first radius is greater than or lesser than the length of second radius; wherein: in a first operational mode, an axial load component will cause each bearing element to contact only a single point of the raceway within the first surface and will position each bearing element so that there is a first clearance gap between the bearing element and the second surface of the raceway; and in a second operational mode, a reversed axial load component will cause each bearing element to contact only a single point of the raceway within the second surface and will position each bearing element so that there is a second clearance gap between the bearing element and the first surface of the raceway. an inner ring; an outer ring including an outer radial surface, an inner radial surface, and a raceway disposed in the inner radial surface, the raceway defined by a first surface and a second surface, and the first surface intersects with the second surface at a point aft of an axial midpoint of the raceway the outer ring including a plurality of apertures that provide a fluid passage between the raceway and an exterior surface of the outer ring, a first end of each of the plurality of apertures substantially aligned with the intersection of the first surface and the second surface; and a plurality of bearing elements disposed between the inner ring and the outer ring the assembly; wherein the first surface has a parti-circular shape with a first radius and a first origin, and the second surface has a parti-circular shape with a second radius and a second origin, and the first origin and second origin are displaced from one another; characterised in that the length of first radius is greater than or lesser than the length of second radius; wherein: in a first operational mode, an axial load component will cause each bearing element to contact only a single point of the raceway within the first surface and will position each bearing element so that there is a first clearance gap between the bearing element and the second surface of the raceway; and in a second operational mode, a reversed axial load component will cause each bearing element to contact only a single point of the raceway within the second surface and will position each bearing element so that there is a second clearance gap between the bearing element and the first surface of the raceway. in a first operational mode, an axial load component will cause each bearing element to contact only a single point of the raceway within the first surface and will position each bearing element so that there is a first clearance gap between the bearing element and the second surface of the raceway; and in a second operational mode, a reversed axial load component will cause each bearing element to contact only a single point of the raceway within the second surface and will position each bearing element so that there is a second clearance gap between the bearing element and the first surface of the raceway.
