摘要: A rolling bearing includes a plurality of rolling elements movably retained at almost the same interval between an inner ring and an outer ring with a cage made of synthetic resin provided interposed therebetween. The rolling bearing further includes, an oil film made of a lubricant, and a grease containing a synthetic oil as a base oil enclosed therein. The lubricant contains at least one additive selected from the group consisting of organic aliphatic acid, organic aliphatic acid derivative and organic phosphorus compound incorporated in a synthetic oil in a proportion of from 0.5 to 10% by weight formed on the surface of the raceways of the inner and outer rings and the surface of the rolling elements, and a grease containing a synthetic oil as a base oil enclosed therein.
