PURPOSE: To retard microstructural change occurring under a rolling contact surface owing to repeated stress load and to improve rolling fatigue life by specifying respective contents of C, V, O, Si, Mn, Mo, Ni, Cu, etc. ;CONSTITUTION: The bearing steel has a composition consisting of, by weight, 0.5-1.5% C, 0.05-1% V, ≤0.002% O, and the balance Fe or further containing, besides the above, one or more kinds selected from 0.05-0.5% Si, 0.05-2% Mn, 0.05-0.5% Mo, 0.05-1% Ni, 0.05-1% Cu, 0.0005-0.01% B, 0.005-0.07% Al, and 0.0005-0.012% N. In this bearing steel, microstructural change occurring under a rolling contact surface owing to repeated stress load can be retarded and rolling fatigue life can be improved and, as a result, a long-life bearing can be obtained.;COPYRIGHT: (C)1994,JPO
