Design features

Eichenberger Easy light leadscrews set new benchmarks for net weight and smooth running properties. Thanks to the rolled aluminium screw and the associated nut made of highperformance technopolymer, the screw unit is a real lightweight. The screw’s robust sliding coating (hard-anodised) makes the screw unit very smooth. With correct lubrication, Efficiency of more than 0.8 can be achieved – an excellent figure for a leadscrew!
Thanks to the special thread geometry, the screw unit is also relatively impervious to dirt and tilting torque.



  • standard: aluminium, hard-anodised
  • on request: other materials and coatings


  • standard: EX100 white
    on request: other materials

Operational temperatures
EX100 –40 to +60 °C

Lead accuracy

  • standard:
    G9 ≤ 0.1 mm/300 mm (in accordance with DIN 69051)
  • on request: other lead accuracies

The efficiency η depends on the helix angle and reaches impressive values over 0.8

Application examples for Eichenberger leadscrews

Thanks to their low weight, excellent smooth running properties and robust thread profile, Eichenberger Easy light leadscrews are suitable for numerous applications including:

  • Drives for doors, gates and windows
  • Handling technology
  • Graphics equipment and devices
  • Construction industry
  • Air-conditioning technology (valve/slide drives)
  • Textile machines
  • Food and packaging industry
  • Electric cylinders (actuators) etc.

Easy light leadscrews are preferred for increased demand from

  • major temperature fluctuation based on climate,
  • impact on environmental conditions such as pollution,
  • limited lubrication options,
  • tilting torque.
