    摘要: The invention provides a grease composition for rolling bearings of automotive electrical equipment or automotive auxiliaries, where a base oil contains as an essential component an alkyldiphenyl ether oil; a thickener is a diurea compound represented by the following formula (1): (wherein R2 is a diphenylmethane group; and R1 and R3, which may be the same or different represent an aromatic hydrocarbon group having 6 to 12 carbon atoms); and an anti-flaking additive that contains an organic sulfonate rust inhibitor and a load carrying additive. The grease composition of the invention can extend the bearing lubrication life even at elevated temperatures and exhibit excellent anti-flaking properties, so that the grease composition can be enclosed in the rolling bearings of automotive electrical equipment or automotive auxiliaries.
