Abstract
A spherical bearing including a ball having an external surface defined by an outside diameter of said ball and an outer race having an inside surface contoured to a shape defined by said external surface of the ball. The inside surface extends between a stud end and a cover end of the outer race. The ball is moveably positioned within the outer race such that the inside surface and the external surface slidably engage one another. The inside surface includes at least one lubrication groove formed therein. The lubrication groove initiates at a first position adjacent to the cover end and terminates at a second position adjacent to the cover end. Remaining portions of the lubrication groove are spaced apart from the stud end.
