Ball screw and method for producing a spindle nut, in particular of a ball screw

A method for making a trunnion for a rocker arm or a finger lever of an internal combustion engine from a piece of rod-shaped ground stock by removal of a peripheral section to produce a flat bearing surface including forming the round stock into a barrel-shaped blank by upsetting, shaping the barrel-shaped blank into a rotationally symmetrical element including a central shoulder having a uniform diameter which is greater than the diameter of the trunnion and removing the peripheral section at any point from the central shoulder by shearing from two sides thereof in an axial direction of the rotationally symmetrical element whereby any cutting plane material from the central shoulder is directed towards a sheared surface whereby the bearing surface is a hardened surface.
