Abstract: A bushing for aircraft landing gear includes a cylindrical wall having an interior surface defining a bore extending between a first and second axial end thereof and a cylindrical recess extending into the interior surface. The bushing includes a cylindrical self-lubricating liner which is substantially flush with the interior surface is disposed in the recess. The cylindrical wall includes a flange that has an annular recess that receives an annular self-lubricating liner that has a planar axial bearing surface. The planar axial bearing surface is coplanar with an inboard axial surface of the flange. The bushing has an electrically conductive path that conducts electrical current and that extends around the cylindrical self-lubricating liner and the annular self-lubricating liner and through the cylindrical wall and the flange.

Abstract: A self-lubricating bearing includes an outer ring having a concave inside surface that defines an interior area of the outer ring. The bearing includes an inner member having a convex exterior surface. The inner member is disposed in the interior area, and the convex exterior surface has a physical vapor deposition coating thereon. A self-lubricating liner is bonded to the concave inside surface. The outer ring is made from a first metallic alloy, and the inner member made from a second metallic alloy.
