GREASE COMPOSITION FOR AUTOMOBILE WHEEL BEARING

摘要

The present invention provides a grease composition for automobile wheel bearings, which contains (a) an urea thickener represented by general formula (1); R1—NHCONH—R2—NHCONH—R3 (wherein R1 and R3 may be the same or different from each other and are each independently an aromatic hydrocarbon group having 6 to 12 carbon atoms, and R2 represents an aromatic hydrocarbon group having 6 to 15 carbon atoms); (b) an organic molybdenum compound; and (c) a base oil. The composition of the present invention can extend the flaking life and lubrication life, and reduce the fretting wear.
