<p>A rolling bearing is protected from premature flaking even under severe conditions of high temperature, high speed and high load, by filling the bearing, which has elements (5) interposed for rotation between an outer race (4) and an inner race, with a lubricant composition, comprising a synthetic base oil, having a kinematic viscosity of 60-160 cSt at 40 DEG C, and 18-28 wt.% of a polyurea thickener. At least one of the inner-race and outer-race raceways is made of the heat hardened steel with an oxygen content not higher than 6ppm. <IMAGE></p> |
