The Screw Jacks of the C-Series in Version N are characterized by a heaving screw. These screws are available with trapezoidal and ball screw drives as well. In both cases the nut of the Screw drive will be integrated in the gear housing. Through the fix assembly of the screw end with the environmental construction the lifting drive is affected.
The advantage of the N-Version is that minimal construction space is needed. On the opposite side of the gear housing a protection tube for the incoming screw is assembled.
A further advantage of the N-version is that in applications with long strokes the nonrotating screw leads to no oscillation.
