ZE 5 kN Rotating Trapezoidal Screw
Engineers are being tasked to “design out” hydraulic systems and “design in” screw jack systems for their pushing, pulling, lifting and holding application needs. The new ZE-Series, particulaly the ZE 5 kN R-Trapezoidal Screw, takes the state of the art Zimm screw jacks to the next level with these industry leading advantages.

Important information
1. If a bellow, spiral spring or double pitch is used; more fitting space is required
2. TR 18x4 is standard, also available: double-pitch, INOX, left-handed, increased screw Tr 20x4 (only for the R version)
3. Factor includes efficiency, ratio and 30% safety
4. For a 4 mm screw pitch
5. To calculate the length of our protective tube length SRO simply use our online configurator: www.zimm.com
