General product features

The ZE-Series takes the state of the art Zimm screw jacks to the next level with these industry leading advantages:

  • Zimm’s dual lubrication system: Provides separate spindle and gearbox cavities allowing for optimum lubrication type to be used in each with the new ZE-Series having a larger gearbox capacity for grease and now oil for longer duty cycles. Separate cavities also completely eliminate lubrication cross contamination in the gearbox
  • Smoother and modern streamlined design: Provides increased heat dissipation, easier paint and corrosion application as well as enhanced wash-down suitability
  • Robust gearbox design allows full capacity mounting in any position
  • Hardened and ground worm shaft is standard
  • Reduced backlash from advanced worm gear design and machining techniques
  • Compatible with existing Z-Series
  • Available in 8 sizes | 5kN – 350kN

Discover the appropriate spindle for your application

The parameters and requirements for the application of your lifting gear are crucial when choosing either a trapezoidal thread or ball screw, especially concerning the following:

  • Duty cycle
  • Repitition accuracy and positioning accuracy
  • Stroke speed
  • Stat. / dyn. loading (Hold load in position or move)
  • Service life and maintenance

Characteristics_Trapezoidal thread or ball screw

Functionality | Rotating and translating spindle

R-Screw | rotating
The spindle is fixed to the worm wheel and rotates with it. The nut therefore moves up and down.

S-Screw | translating
The worm wheel has an internal thread and transforms rotary motion into linear movements as long as the spindle is prevented from rotating.
