Abstract
A method of producing rolling elements for a rolling bearing comprises mixing to process rounded elements made of steel balls and spherical rolling elements having outer diameter portion portion becoming a rolling contact face. The rolling contact face has curvatures in an axial direction and a radial direction normal to the axial direction, and has at least one plane. The thus mixed elements are placed and processed in a space between two processing boards opposing each other via the determined space. Thereby, the surfaces of the rounded balls and the rolling elements are processed to be rounded.

A method of producing rolling elements for a rolling bearing, comprising:
- mixing rounded elements made of steel balls and spherical rolling elements each of which has rolling contact faces having curvatures in an axial direction thereof and a radial direction normal to the axial direction and has at least one plane;
- and
- placing and processing the thus mixed elements into a space between two processing discs opposing each other, whereby the surfaces of the rounded elements and the spherical rolling elements are processed to be rounded.
