Patent ID: 6858096

Claim:
A method for producing a rolling element for a continuously variable transmission, the rolling element including a plurality of rolling members having rolling contact portions coming into rolling contact with each other via lubricating oil, at least one of the rolling contract portions including an outer surface layer having a surface microhardness of not less than Hv 750, a surface residual compressive stress of not less than 1000 MPa and a residual austenite content of not more than 10% by volume, the method comprising: subjecting a workpiece to either one of carburizing-quenching and carbonitriding-quenching; subjecting an outer surface of the workpiece subjected to either one of carburizing-quenching and carbonitriding-quenching to shot peening; and subjecting the outer surface of the workpiece subjected to shot peening to finish grinding so as to provide the rolling element having the outer surface layer having a surface microhardness of not less than Hv 750, a surface residual compressive stress of not less than 1000 MPa and a residual austenite content of not more than 10% by volume.
