Abstract: A spherical plain bearing includes an outer ring having a concave interior spherical surface, and an inner member having a convex exterior spherical surface. The inner member is pivotally disposed in the outer ring such that the inner member and the outer ring are angularly misalignable relative to one another. The spherical plain bearing includes an angular misalignment restraint system which includes an inner member restraint feature on the inner member and an outer ring restraint feature on the outer member. The first and second portions are spaced apart when the inner member and the outer ring are angularly misaligned relative to one another by less than a predetermined maximum angle θ, and come into abutment when the inner member and the outer ring are angularly misaligned relative to one another by angle θ. The abutment prevents any further relative angular misalignment of the inner member and the outer ring.
