High quality and suitable for many applications, INKOMA screw jack systems are perfect for lifting, lowering, and push or pull movements.

The compact size SEL Series Cubic Worm Screw Jack is made for a load range of 5 kN-100kN. The cubic design and universal mounting facilitates alignment of the drives during installation. The typical application for the small SEL Series is where moderate loads have to be accurately lifted, precisely positioned and safety held at medium duty cycles, moderate lifting speeds and small confined spaces.

Features:

  • Mechanical Screw Jack European Light Series
  • European Light Series (5-100 kN)
  • Mechanical screw jack with housing in high strenght Aluminium alloy.
  • 5 different sizes (SEL5, SEL10, SEL25, SEL50, SEL100).
  • 3 different reduction ratios (1/5, 1/10, 1/30).
  • Lifting/thrust capacity up to 100 kN.
  • Lifting/thrust speed up to 15200 mm/min.
  • “T” version, featuring Trapezoidal spindle (self-locking).
  • “S” version, featuring Ball Screw spindle (high efficiency).
  • Grease lubricated.
  • Modular and compact cubical design provides maximum adaptability to each specific application.
  • Wide range of standard accessories/features.
  • Special execution on request: please contact us.
