<p>A slide way lubricant composition includes at least (a) a hydrotreated petroleum having a viscosity of from about 10 cSt to about 250 cSt as measured at 40 °C and consisting predominantly of hydrocarbons having from about 15 to about 50 carbon atoms per molecule and (b) a polymeric synthetic ester having an average molecular weight of at least about 200,000. The hydrotreated petroleum may be employed in an amount of from about 97.8 to about 99.4 weight percent and the ester may be employed in the composition in an amount of from about 0.6 to about 2.2 weight percent. The ester may be derived from the reaction between a dicarboxylic acid and a polyhydric alcohol. The composition may further include an adhesion additive having an average molecular weight of at least about 1,000,000 and a high pressure agent, such as a trisulfide. A demulsibility agent may also be employed. Another embodiment is a method of making the slide way lubricant composition which includes heating the hydrotreated petroleum to a temperature of from about 90 °F to about 120 °F and blending the polymeric synthetic ester and any other desired components or additives into the headed hydrotreated petroleum. Another embodiment is a method of lubricating a slide way having bearings which includes applying a lubricant composition to the bearings wherein the lubricant composition includes the above described hydrotreated petroleum.</p> |
