PROBLEM TO BE SOLVED: To provide a grease composition that exhibits excellent low friction property even with a low molybdenum content when used under severe sliding conditions such as high speed and high surface pressure, and a bearing, a universal joint, and a linear motion device obtained by enclosing the grease composition.SOLUTION: The grease-enclosed bearing 1 is obtained by enclosing the grease composition 7 at least in a periphery of a rolling element 4. The grease composition 7 includes a base oil, a thickener, and an additive. The additive includes molybdenum dithiocarbamate and sodium dithiocarbamate. The molybdenum content based on the whole amount of grease composition is ≤0.06 wt.%.
摘要:
The invention relates to a lubricating composition comprising (a) at least 0.05 wt % of a non-aromatic metal carboxylate, wherein the metal carboxylate is derived from a branched carboxylic acid, and (b) an oil of lubricating viscosity. The invention further provides for the use of the lubricating composition for lubricating a limited slip differential.
