Abstract: A spherical plain bearing includes an outer ring formed from metal and having a concave first bearing surface, and an inner ring having a convex second bearing surface in sliding disposition to the first bearing surface. One of the members is made from titanium alloy and has a treated bearing surface. The other bearing surface has a lubrication liner. The liner may be made from PTFE, such as a fabric of PTFE and polyaramid fibers. The treated surface may be TiN provided by physical vapor deposition.

Abstract: In a spherical plain bearing, an outer ring has a length and an outer periphery defining a first shoulder located at one end along the length and a second shoulder located at a second end along the length. The second end is generally opposite the first end with the first and second shoulders being sized to pressingly engage a housing wall. The housing wall defines a bore into which the spherical plain bearing is positioned. The outer periphery of the outer ring further defines a first staking lip extending radially outwardly from the outer periphery at a first distal end thereof and a second staking lip extending radially outwardly from the outer periphery at a second distal end thereof generally opposite the first distal end.
