Abstract
The present invention relates to a ball screw spindle (10) for a ball screw drive, a linear drive (1) with such a ball screw spindle (10), and a manufacturing method (100) for such a ball screw spindle (10). A spindle body (12) is provided, which has at least one guide groove (16) for spherical rolling elements on a cylindrical surface (14), and a separate coupling element (18) for coupling to a drive (4), which is arranged coaxially with the spindle body (12) at one end (20) of the spindle body (12). According to the invention, a separate stop disk (22), also arranged at the end (20) of the spindle body (12), is provided, which is secured against rotation relative to the spindle body (12) by means of the coupling element (18) which is fixedly connected to the spindle body (12).
