Abstract
A linear unit for applying an axially acting force, composed of a rotational/translational gear (2) which has a threaded spindle (18) and a threaded nut (19) which are arranged in a gear housing (22), and of an electric motor (1) with a rotor (12) and with a stator (11) which are arranged in an electric motor housing (10). In order to simplify the set-up of the linear unit, while at the same time reducing the packaging space required, according to the invention the threaded spindle (18) is mounted rotatably and axially fixedly inside the gear housing (22) and is connected to the rotor (12) outside the gear housing (22).
