A hinge assembly for a vehicle track, conveyor chain or the like has at least one bearing lacquer coated onto at least one of the mutually contacting surfaces of the pin or bushing and having a binder or carrier of the polyamide/polyimide type or of a molecular structure with alternating amide and imide monomers. A filler of molybdenum disulfide, molybdenum oxides and/or hydroxides and graphite is provided in the carrier or binder. Other lubrication is not required and the bearing lacquer has a long life.
