    摘要： A rolling bearing for an HDD being excellent in the resistance to fretting wear, capable of lowering the torque and relieving the torque change and having a long life while exerting no undesirable effect on various bearing properties. A rolling bearing for hard disk drives wherein a cage 7 supports a plural number of rolling elements 5 located between an inner ring 2 and an outer ring 4 and sealing members 6,6 fixed to the both ends in the axial direction of one of said inner ring 2 and said outer ring 4 are opposite to each other, wherein a lubricating oil has been injected into the bearing space formed between said sealing members 6,6 at the both ends in the axial direction so as to amount to 1 to 50% by volume of the bearing space.

    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.
