Abstract
A bearing assembly having an axially extending axis of rotation is provided having an inner ring, an outer ring, and a plurality of bearing elements. The plurality of bearing elements are disposed between the inner ring and the outer ring. The outer ring includes an outer radial surface, an inner radial surface, and a raceway disposed in the inner radial surface. The raceway is 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 includes 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 is substantially aligned with the intersection of the first surface and the second surface.
