Abstract
A bearing housing assembly includes a bearing housing and a bearing assembly. The housing extends along an axis and has a cross-bore surface defining a cross-bore to receive lubricant and a feed groove surface defining a feed groove. The feed groove surface has a constant radial portion extending circumferentially about a majority of the axis with a first groove radius that is constant and an expanded radial portion extending from the constant radial portion circumferentially about the axis with a second groove radius larger than the first groove radius. The bearing housing also has an interior surface having an interior radius smaller than the first groove radius and defining an interior. The bearing assembly is disposed in the interior and includes an outer race having a receiving groove surface defining a receiving groove, an inner race, and a rolling element disposed between the outer race and the inner race.
