• torsion free, purely axial generation of the clamping force

  • high clamping forces in compact design, accurate repeatability

  • long service life without connecting to a pressure source

  • due to leakproof seal systems pressure safe = autarkic system

  • to use as a machine part i. e. on rotating arbours

  • resulting clamping force is independent of the stroke

  • no friction in the thread since the Hydraulic Nut is not turned under load (no thread wear)

  • SCHAAF-Hydraulic Nuts can be serviced by the customer on site
