PROBLEM TO BE SOLVED: To obtain a rolling bearing showing excellent heat resistance and reduced in the formation of a mist of a grease by packing a lubricating grease having a specified kneading consistency into an all-ball rolling bearing composed of a pair of inner and outer guide rings and a plurality of balls incorporated in the guides without limitation on the spacing in the direction of the peripheries of the guides. SOLUTION: Prepared is a lubricating grease having a consistency of 180-260 and comprising at least one grease base selected from among a mineral oil, a synthetic hydrocarbon oil, and an ether oil, 15-30 wt.% thickener, a rust preventive selected from among a metal organic sulfonate, an ester, etc., a nitrogenous compound antioxidant or a phenolic antioxidant, an extreme pressure additive, a wear inhibitor, an oiliness agent, etc. This grease is packed into an all-ball rolling bearing composed of a pair of inner and outer guide rings and a plurality of balls incorporated in the guides without limitation on the spacing in the direction of the peripheries of the guides. The thickener used is a lithium soap, such as lithium laurate or lithium stearate, containing no hydroxy in the structure.
