NEFF MH/JH-series
Screw jack

  • Lifting screw jack, axial or rotating screw
  • Up to 250kN. Ingoing rpm up to 3000 min-1
  • Trapezoidal spindle or ballscrew

NEFF spindle lifting element (MH/JH-series) with standing rotating spindle or non-rotating moving spindle for loads up to 250 kN. The NEFF spindle lifting elements (MH/JH-series) are provided with precisely machined worm wheels, which have separate lubrication with respect to the spindle. As a result, higher input speeds are permissible. The cubic design and machined housing on all sides simplifies actuator alignment during installation.
