Abstract

A thrust washer is combined with a seal for preventing contaminants from entering into the assembly and doing corrosion damage. In one embodiment, a spring shackle bracket assembly thrust washer is provided with an elastomeric seal bonded thereto and having a sealing lip extending from the I.D. of the washer axially into the space between the spring eye and the shackle pin. In addition, a layer of the seal material on a radial face of the washer can prevent wear between the washer and the adjacent bracket.
