摘要

The present invention relates to a method for manufacturing a steel wire for bearings, a method for manufacturing steel wire for bearings, a heat treatment method for bearings, a method for crack diffusion treatment of bearings and cast steel bearings, and more particularly, high strength high carbon having excellent wear resistance, fatigue resistance, and the like. Heat treatment method for manufacturing bearing steel, high carbon bearing steel wire rod provided in the heat treatment and the method of manufacturing the wire rod and the crack diffusion method of the cast steel provided for the production of high carbon bearing steel and bearing wire rod manufactured from the heat treatment It is about.;Bearing heat treatment method of the present invention, the step of quenching the bearing-shaped steel parts comprising carbon: 0.50 ~ 1.20% by weight and silicon: 1.0 ~ 2.0% by weight; Maintaining the quenched component for at least 1 minute; And distributing at least 10 minutes at a temperature of Ms-100 ° C. to Ms for the retained parts.;Bearing, toughness, fatigue characteristics, heat treatment, distribution treatment
