To provide a rolling bearing for a man-made satellite which is free from the damages, e.g., formation of the band mark on the surfaces of the rolling elements, and the losing of the luster of the surfaces thereof. There is provided a rolling bearing, which is used mainly for a man-made satellite, includes an outer ring, an inner ring, and rolling elements. The parent material of those components is martensitic stainless steel. Of those components, at least the rolling elements are processed to have nitride surface layers formed over their surfaces. A hardness of the nitride surface layer is Hv1200 to 1500.

Rolling bearing

An anti-electrolytic corrosion rolling bearing having at least an outer race, an inner race, and rolling elements interposed between the outer and inner races, which has an insulating body on at least one of the outer peripheral surface of the outer race, the inner peripheral surface of the inner race, and the side surfaces of the outer race and inner race, said insulating body being composed of an insulating film or insulating member each containing at least one of a thermoplastic synthetic resin, a rubber, and a thermoplastic elastomer as a base material and having a resistivity of not less than 1.times.10.sup.13 .OMEGA..multidot.cm and a thermal conductivity of not less than 0.5 W/m.multidot.K.
