Type N

Type N

The N-Type worm gear screw jacks are characterized by the lifting spindle.
Like all other NEFF-ball screws, Type N of the M-J series is available with trapezoidal ball screws as well as with ball screw drives.
That is, the nut thread of the ball screw is in the center of the worm gear. Protected against twisting, the spindle is executing the lifting movement: the not rotating spindle is right through the gearbox housing.

On the side of the load, worm gear screw jacks type N can be mounted with little required space. On the opposite side, installation space is required for the threaded spindle entering a protective tube.

One advantage of this type:  vibrations, which might be triggered by the rotation spindle and long lifts, are impossible.
