Abstract:
A screw element of a ball screw mechanism includes a lead screw which, at an axial end, is joined to a rod element using a friction welding process. In order to improve the friction-welded joint, prior to the friction welding process, the lead screw has a circumferential groove on the end face facing the rod element.
