ABSTRACT:
A base material for a lubricant mixture or a lubricant for use in the fifth wheel plate/king pin plate bearing area including polybutene, polybutylene and/or other similar elastomer and/or viscous non drying liquid, the combined mixture with a Saybolt Universal viscosity at 99.degree. C. using ASTM method D-2161, of greater than 500 SUS. In addition, the lubricant may include synthetic oil(s), mineral oil(s), natural oil(s), polyols and/or esters, in any combination, having a final, mixed or blended viscosity of between 2-60 measured in centistokes at 150.degree. C. using ASTM method D-445 and thermoplastic polymer(s) and/or wax(es) with a melting point of between 160.degree. F.-500.degree. F. The above combination of materials may constitute 60 percent or more by weight of the final lubricant mixture.
