ABSTRACT:
A manufacturing method of a thin component is characterized by heating a thin component, and thereafter, while sizing with molds and using molds as cooling media, performing one of quenching and isothermal transformation processes on thin component. Thus, a manufacturing method of a thin component without warping or deformation in heat treatment with even and high hardness, a bearing ring, a thrust needle roller bearing, a manufacturing method of a rolling bearing ring, a rolling bearing ring, and a rolling bearing can be obtained.
