Telescopic Screw Drive S-TEG

2-stage synchronously extending telescopic screw drive as glide screw drive version or as ball screw drive version.
As proven “N” design version – “Lifting screw” - or as non-rotating variant of the “VK” design, optionally with safety nut
and integrated limit switches.

Standardised connecting options on request for gear, toothed belt or for the direct connection of a drive motor by means of
a motor adapter flange or coupling.
The different variants can be selected on the basis of the product code.

General technical data:

- The intelligent drive unit ensures continuous torque and clearance throughout the entire stroke.
- Reduced friction values due to Teflon-coated aluminium materials (glide screw version)
- The safety nuts for the glide screw version may optionally be set for fracture or wear.
- For the ball screw version, nuts from the standard product range are used, thus ensuring availability of stock goods and
quick replacement.
