NEFF MH/JH-N
Screw jack

• Lifting screw jack, axial screw
• Lifting capacities of 5 to 250 kN
• Ingoing speed up to 3000 min-1

NEFF spindle lifting element (MH/JH-N) with non-rotating moving spindle for loads up to 250 kN. The NEFF spindle lifting elements (MH/JH-N) 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.
