Abstract
A sealed spherical bearing is disclosed, having a race and a ball disposed therein. A seal between the race and the ball inhibits the ingress of contaminants into the spherical bearing. The seal has a first edge. The first edge is secured to a retainer, which is press-fit into an annular groove defined by the race. The ball and the race are rotatable relative to each other. A second edge of the seal is seated in a second annular groove defined the ball. A lubricant is disposed inside the second annular groove. A convex surface of the ball and a concave surface of the race form a sliding surface. A self-lubricating treatment is applied to one or more of the sliding surfaces.
