If the tribological coating is applied to the outer surface of the bearing outer ring, it is made of a material that is metallurgically incompatible with the material from which the housing containing the bearing is made. The coating includes one or more of the following: Cr, W, Mo, or Nb, or nitrides, carbides, oxides, or sulfides of Cr, W, Mo, or Nb.
