Abstract: A bearing and a method for fabricating a bearing. The bearing is intended to be used in office automation equipment and the like is improved in impact resistance and load capacity. Its rotational accuracy will not deteriorate in long-term use and its quietness can be maintained over a long period of time. The bearing is an anti-friction bearing located between portions supporting a load and in relative motion to each other. The anti-friction bearing has an outer ring of 30 mm or less in diameter, in which high carbon chromium bearing steel constituting the anti-friction bearing includes the following compositions: C of 0.90-1.30 wt %, Si of 0.40-1.20 wt %, Mn of 0.90-1.0 wt %, and Cr of 0.90-1.70 wt %. After quenching, the tempering temperature used for this bearing is maintained in the range of 170° C. and 250° C. so that the amount of retained austenite in the surface layer after heat treatment is stabilized at 6 by volume or less.
