摘要： As a steel material for an inner race, an outer race and a rolling element constituting a rolling bearing, there is used one containing carbon (C) and chromium (Cr) in an amount of 0.65 wt % to 1.10 wt % and 2.0 wt % to 6.0 wt %, respectively. At least one of the inner race, the outer race and the rolling element is formed from the steel material. The inner race, outer race and the rolling element thus formed is then subjected to hardening, tempering and polishing. Further, a chromium oxide layer (Cr2O3) having a thickness of 5 nm to 300 nm is formed on a race track surface of at least one of the inner race, the outer race and the rolling element. If the rolling bearing is used in operation under the lubrication at a high traction coefficient with water mixed therein, finely particulate molybdenum carbide and/or vanadium carbide having a particle diameter of 50 nm to 300 nm is distributed in the matrix.
