ABSTRACT:
A process of producing an outer joint part formed in a non-chip forming way from a plate metal member and having circumferentially distributed, outwardly formed ball tracks. In one or several connected process stages, a plate metal bar is formed into a rotary member whose axial end regions are deformed so as to differ in cross-section from a central portion and that in at least one separate process stage, the ball tracks are formed in an axial region between the deformed end regions.
