A grease composition having improved yield, dropping point, and functional life when used in an antifriction bearing at elevated temperatures comprising a base oil of lubricating viscosity thickened with a specially-defined aryl diurea obtained as the result of reacting critical molar ratios of a mixture of p-toluidine and p-chloroaniline with a toluene diisocyanate. In an especially preferred embodiment the grease composition additionally contains precipitated calcium carbonate in an amount sufficient to obtain a grease having improved e.p. (extreme pressure) properties and an extended functional life. |
