Abstract: A rolling bearing is composed of an outer race having an inner-race raceway on an outer peripheral wall thereof, an outer race having an outer-race raceway on an inner peripheral wall thereof, a plurality of rolling elements interposed for rotation between the outer-race raceway and the inner race, and a lubricant composition filled in a space, which is defined between the inner-race raceway and the outer-race raceway, at a position where the plurality of rolling elements are disposed. The rolling bearing features: (a) at least one of the inner-race and outer-race raceways is made of steel having an oxygen content not higher than 6 ppm; (b) at least a raceway surface of said at least one raceway has been hardened by heat treatment; (c) the lubricant composition comprises as a base oil a synthetic lubricant having a kinematic viscosity of 60-160 cSt at 40.degree. C.; and (d) the lubricant composition further comprises 18-28 wt. % of a thickener which comprises a polyurea compound.

Abstract: A rolling bearing is composed of an outer race, an inner race and rolling elements interposed between the outer race and the inner race. A lubricant composition comprising a polyether lubricant as a base oil is filled in the bearing. Preferably, the polyether lubricant has a kinematic viscosity 90-160 cSt at 40.degree. C.
