patent specification: "Constant velocity joint grease composition and constant velocity joint in which the constant velocity joint grease composition is sealed". The present invention provides a constant speed joint grease composition containing: a lubricating base oil, at least one thickening agent, urethane thickening agents and urea / urethane thickening agents; an organic molybdenum; zinc dithiophosphate; a polysulfide and triglyceride. The organic molybdenum content is 1,000 to 5,000 ppm by weight in terms of molybdenum element based on the total mass of the grease composition. This grease composition is capable of exhibiting sufficient characteristics even in cases where the amount of an additive such as a molybdenum disulfide is reduced. |
