The Ludeca ROTALIGN Pro Laser Shaft Alignment Tool lets you align machine trains of up to six machines, calculating which machine feet to move in order to reduce work to a minimum. It not only measures soft foot but also analyzes it and suggests corrective action. It can even compute thermal growth for you. But ROTALIGN® PRO does not stop at the alignment of rotating machines: it also features an optional program for accurate single-pass straightness measurement.
Ludeca ROTALIGN Pro Features
  • Aligns horizontal & vertical machines
  • Aligns coupled & uncoupled shafts
  • Rotate shafts only a quarter-turn in any position
  • Machine train alignment
  • Built-in soft foot expertise
  • Thermal growth computation
  • Cordless measurement
  • Cardan shaft alignment
  • Measure straightness with ease
  • Take Command with PC software
