Abstract
A grease composition for constant velocity joints comprises the following components: (a) a base oil; (b) a diurea type thickening agent; (c) a molybdenum sulfurized dialkyl dithiocarbamate; (d) molybdenum disulfide; (e) at least one sulfur-phosphorus-containing extreme-pressure agent selected from the group consisting of zinc dithiophosphate compounds and thiophosphates; and (f) a fatty acid amide. The grease composition of the present invention has a high ability of reducing the induced thrust force and is excellent in the durability.
