Method for production of outer ring and inner ring for antifriction bearings, involves placing disk made of metal so that radially bent edge is formed around central rotation axle of disk

摘要

The method involves placing a disk (3) made of metal so that a radially bent edge is formed around central rotation axle of the disk. The disk is formed by a shaping process by rollers, where a cylinder section is formed by the disk. The edge formed by the adjustment remains within interior of the cylinder section.
