Abstract
A method for producing a joint outer part by means of flow forming is provided. A blank is arranged on a contour mandrel such that it cannot rotate with respect to the contour mandrel. The contour mandrel is driven in such a way that the blank and the contour mandrel rotate about a common axis. The blank is shaped at least partially with the aid of a flow forming roller which acts on the blank in order to form the joint outer part. At least one track is formed with a concave region in the joint outer part.
