The measuring slide has been equipped with our approved vacuum air bearing system, where the guide way surfaces are held by vacuum and simultaneously being accurately lifted off with a precise air film. The STRAIGHT-lite is now held with a fine break in its position without affecting the air film. The air unit SA 100 is required for the processing of air pressure and the generating of vacuum.


Application areas:

  • Measuring instrument for quality assurance under workshop to laboratory conditions
  • Calibration and verification of test and measurement equipment
  • Align and control / recording of straightness and parallelism of linear guideways or linear axes
  • Measurement of straightness, parallelism and torsion on workpieces and assemblies
  • Alignment of workpieces on clamping devices and plate changers



  • High precise, wear-free air bearing of the measuring slide
  • High air bearing stability and rigidity
  • Unmatched repeatability
  • Resistance-free movement of the measuring slide
  • Minimal air bearing noise
  • Versatile measurement capabilities with the optional equipment CARBON-stand
  • Already owned measuring straight edges can be used
  • Flexible handling on the entire hard stone test plate
  • Incl. calibration SCS (ISO/IEC 17025)


Kunz precision AG is a leader in the revision and calibration of hard stone test plates and test equipment.

To make measuring with the measuring device STAIGHT-line even more easy and efficient, you can order the CARBON-stand as a practical option. The bracket is adjusted to the correct height on the vertical column with knurled screws, and then clamped in the correct position.
