Abstract: Combining a metal based friction modifier, such as a molybdenum dialkyldithiocarbamate, and certain esters of hydroxy carboxylic acids, such as short chain alkyl esters of citric or tartaric acid, e.g., tributyl citrate, has a synergistic effect on lowering the friction coefficient of lubricating oils allowing one to reduce the amount of metal based friction modifier needed to adequately formulate a lubricant with low friction characteristics.

Abstract: 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 R 2 is a diphenylmethane group; and R 1 and R 3 , 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.
