ABSTRACT:
A grease composition for a constant velocity joint contains a base oil containing 2 to 25 wt.% of a thickener based on total weight of the composition, 0.5 to 20 wt.% of boron nitride powders based on total weight of the composition, and 0.1 to 10 wt.% of an extreme pressure agent based on total weight of the composition selected from the group consisting of molybdenum dithiocarbamate, a sulfur and phosphorus-containing extreme pressure agent, and mixtures thereof. The sulfur and phosphorus-containing extreme pressure agent consists of a sulfur-containing compound and a phosphorus-containing compound. The sulfur-containing compound is selected from the group consisting of a sulfide of fats and oils, a polysulfide, and mixtures thereof. The phosphorus-containing compound is selected from the group consisting of a phosphate, a phosphite, and mixtures thereof.
