The sliding door drive includes at least one carriage (2), driven by at least one lead screw (3) with a longitudinal axis X2, a lead nut (4) configured to move along the lead screw (3) along the X2 axis. The axial force from the running nut (4) is transmitted to the carriage (2) through the lever, in the groove of which the running nut (4) is installed, made with the possibility of sliding in the groove and limited rotation about the Y and Z axes. The running nut (4) contains protruding elements for fixation from axial movement relative to the lever.
