Grease composition for rolling bearings, and rolling bearing

Abstract

The present invention provides a grease composition for rolling bearings, comprising a base oil; as a thickener, a complex amido-lithium soap; as antioxidants, 0.5 to 5% by mass of an amine-based antioxidant and 0.5 to 5% by mass of a phenol-based antioxidant, based on the total mass of the composition; and as rust inhibitors, 0.1 to 5% by mass of a carboxylic acid-based rust inhibitor, 0.1 to 5% by mass of a carboxylate-based rust inhibitor, and 0.1 to 3% by mass of an amine salt of a fatty acid, based on the total mass of the composition, wherein a 60-stroke worked penetration is 260 to 320 as measured according to JIS K 2220 7.
