A ball screw nut having a tubular sheet metal body with a thread profile and being optionally encapsulated in plastic. This sheet metal body is formed of a sheet metal part that includes the thread profile and a ball-returning piece inserted therein, which is designed as an additional sheet metal part.

Ball screw nut

The invention relates to a method for producing a spindle for a ball screw, including the following steps: &#x2014;introducing, at least in sections, a thread profile into a flat material section, &#x2014;shaping the material section to a hollow cylindrical case, two lateral edges of the hollow cylindrical case abutting each other and the thread profile being oriented radially outwards, &#x2014;connecting the two lateral edges of the hollow cylindrical case, and &#x2014;forming, at least in sections, a supporting structure on a radially inner face of the hollow cylindrical case to finish the spindle. A spindle for a ball screw in hybrid design can thus be manufactured in a simple manner. The spindle can be produced cost-effectively and yet has high wear resistance and excellent mechanical load-bearing capacity as well as light weight. The invention further relates to a spindle manufactured according to the invention, for use in a ball screw.
