ABSTRACT:
A resilient bushing with long fatigue life comprises an outer rigid member having curvilinear inner surface portions and inner rigid member having curvilinear outer surface portions. At least one of said surface portions has a surface roughness height rating measured by SAE Standard J448a. Said surface roughness height rating is provided by sandblasting said surface portions of a metal member, and thereafter forming on said surface portions a phosphate coating. An elastomeric insert is compressively positioned between said inner surface portions of the outer member and said outer surface portions of the inner member.
