• torsion free, purely axial generation of the clamping force

  • high clamping forces in compact design, accurate repeatability

  • long service life without constant pumping due to leakproof seal systems (short duty cycle of the pump)

  • completely even distribution of the clamping forces

  • 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)

  • quick and easy operation, even large Hydraulic Nuts with appropriate hand or motor pump
  • SCHAAF-Hydraulic Nuts can be serviced by the customer on site
