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.


  • 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 straight- ness with ease!
  • Take Command with PC software!
