Abstract

The invention relates to a lubricant composition for application onto the surface of drive elements, the lubricant composition containing a base oil and a silasesquioxane. The composition is suitable for preventing, reducing or avoiding fatigue phenomena in the material of drive elements, such as gray staining, false brinelling and white etching cracks.
