    摘要: A lithium complex grease for rolling bearings which has high dropping points and is capable of maintaining for a long time an excellent stability of a thickener micell under a high temperature, high adhesion, heat resistance, water resistance, rust resistance, load resistance, low noises and other high-level properties and a method of producing such lithium complex grease. The lithium complex greases are characterized in that base greases containing a base oil, a fatty acid having 12 to 24 carbon atoms, a dicarboxylic acid having 4 to 12 carbon atoms and/or a dicarboxylic acid ester and a lithium hydroxide are thickened with a phosphate ester and/or a phosphite ester. A method of producing the lithium complex greases is characterized in that the base greases having the above composition are added by the phosphate ester and/or the phosphite ester, and thickened under a reaction at a temperature of more than 210.degree. C. (410.degree. F.).
