A mechanical linear drive system for generating a defined linear movement of a driven force transfer element (16) has a spindle drive, the threaded spindle (7) of which is supported in a profiled tubular structure (1) of stable shape, closed off at the end by bearing flanges (9) and provided with a linear slit through which the force transfer element, drivingly coupled in the longitudinal direction of the tubular structure by the spindle nut (11) of the spindle drive, protrudes to the outside out of the tubular structure. To permit adaptation to conditions imposed by various kinds of use, the arrangement is such that the spindle nut is supported rotatably and axially immovably on the force transfer element, and that a drive means that is joined with the force transfer element is coupled with the spindle nut (11) via a gearing means (18, 19, 20) located on the force transfer element (16). This drive means, and a further drive means (10) that may be provided for driving the threaded spindle, makes it possible to generate the most varied kinds of linear movements. A plurality of spindle nuts can also be provided on the threaded spindle, or the threaded spindle can be divided into a plurality of spindle portions.
