Screw jack

  • Lifting screw jack, axial screw
  • Lifting capacities of 2,5 to 500 kN
  • Ingoing speed up to 1500 min-1

NEFF screw jack (type M/J-N) with axial lifting screw or rotating screw for lifting capacities from 2,5 up to 500 kN. The NEFF M/J-N screw jack is used wherever loads have to be positioned under moderate duty cycles and little dynamic. The cubical design and the all-round handling facilitate an easy alignment of the drives during installation. 

Construction forms NEFF screw jack M/J-N

  • Type N : Non-rotating moving screw
