Abstract:
1. A method of lubricating a non-metal surface of a slideway component, the method comprising applying a lubricant composition to the slideway component, the lubricant composition comprising: a base oil; a metal-free friction modifier selected from the group consisting of glyoxalidines, glycerides, and combinations thereof, wherein the glycerides are of the formula: wherein each R is independently selected from the group consisting of H and C(O)R′ wherein R′ may be a saturated or an unsaturated alkyl group having from 3 to 23 carbon atoms; a metal-free and sulfur-free, phosphorus containing anti-wear/extreme pressure agent; wherein the composition provides a lower coefficient of friction for non-metal sliding surfaces than for metal sliding surfaces, and wherein the lubricating composition is free of or essentially free of metal-containing friction modifiers.
