Abstract
A motion nut for a lifting device, especially a car jack, in which a basic body has an internal thread and a threaded spindle is seated in the internal thread. The basic body together with the internal thread is a single unit component formed of at least two separate material components of different materials. The two separate material components form an internal thread region part and an external part, so that properties of the internal thread region is selectable different from properties of the external part. The properties of the thread being selectable for reduced friction and the properties of the external part being selectable for increased strength and stiffness.
