Grease composition for constant velocity joint

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.

A grease composition for constant velocity joints comprising: (a) a base oil; (b) a diurea thickener of the formula (1):

Grease composition for constant velocity joints

A grease composition for constant-velocity joints which is prepared by blending a lube base oil with (A) a urea-urethane thickening agent comprising a mixture of

Grease composition for constant-velocity joints

A grease composition for constant velocity joint is a particular combination of a urea grease composed of a lubricating oil and a urea base thickener with (A) molybdenum sulfide dialkyldithiocarbamate, (B) molybdenum disulfide, (C) zinc dithiophosphate and (D) an oiliness agent of at least one vegetable oils and fats and can attain not only reduction of induced thrust but also improvement of flaking resistance.
