ABSTRACT:
A socket bearing for use in a ball and socket joint includes a plurality of lubrication grooves, some having annular, others having helical, orientations over the interior surface thereof. In a preferred form, the socket is cup-shaped having a spherical interior surface, and includes three parallel radially oriented annular grooves intersected by three longitudinally oriented helical grooves. Each groove defines a radius, and each pair of adjacent grooves defines a land between the grooves. An interface boundary is defined by one side of one groove and the land associated with the side of that particular groove. The interface boundary is radiused, wherein the radius thereof has a value of at least fifty percent of that of the radius of the groove.
