PROBLEM TO BE SOLVED: To provide a grease composition for a rolling bearing, with which acoustic life of a rolling bearing in a high temperature range is improved, and a rolling bearing filled with the same.SOLUTION: The grease composition for a rolling bearing contains a base oil, a predetermined urea-based thickener and a metal deactivator. The aniline point of the base oil is 110°C or more. The urea-based thickener is at least one kind of diurea compound selected from a diurea compound represented by the following formula (1): R-NHCONH-R-NHCONH-R(1), where Rand Rmay be same or different from each other and represent a Calkyl group, a Ccycloalkyl group or a Caryl group and Rrepresents bivalent aromatic hydrocarbon group having 6 to 15 carbon atoms.SELECTED DRAWING: None |
