A method for producing a threaded nut () of a screw drive, in particular of a ball screw (), which threaded nut () has, on one axial end, a recess () which extends over a circumferential segment and which is open at the end side, wherein said recess () is delimited radially by a circumferential wall of the threaded nut (), and wherein said recess () is delimited axially by a base () formed on the threaded nut (), and wherein said recess () is delimited in the circumferential direction by a stop surface (), which is formed on the threaded nut (), for a projection (), produced according to the following steps: a blank is deformed in a deformation process by deformation of material so as to form the recess (), wherein the base () and the stop surface () and the circumferential wall are integrally connected to one another.

A ball screw (), having a threaded spindle () which is mounted in a rolling fashion by balls () on a threaded nut () and which is supported on an axial bearing (), wherein the threaded spindle () is axially supported with its first bearing surface (), which is convexly shaped with a radius of curvature (R), on a preferably conically designed second bearing surface (), wherein the first bearing surface () and the second bearing surface () make contact with one another along a contact path (), wherein a quotient formed from the ratio of the radius of curvature (R) to the radius (R) of the contact path () assumes values of between 1.2 and 2.4 inclusive.
