  • Uniform speed


SCREW JACKS WITH BASE

  • Uniform translation speed.
  • High speed.
  • High efficency.
  • Capacity from 10 kN to 300 kN.
  • Gear ratios: from 5:1 to 32:1.
  • Standard model: Body in Nodular Cast Iron, Worm Screw in high resistance Stainless Steel, Worm Gear in special Bronze, Work Screw in high resistance Steel.
  • Stainless Steel model: Body in Cast Stainless Steel, Worm Screw in high resistance Stainless Steel, Worm Gear in special Bronze, Work Screw hardened high tensile steel and extending terminal in Stainless Steel.
  • Safety stop to avoid Work Screw extraction (Do not use as power stop).
  • Work Screw threads protection.
  • Screw Jacks complete with greaser nipples and end shaft keys.
