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 10 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.
