Rack-and-Pinion Systems of WITTENSTEIN alpha

The perfect symbiosis of state-of-the-art technology and many years of experience. Our specialist knowledge extends from the coupling of gearbox, motor, pinion and rack to complete system solutions. 30 years of experience in the fields of gearbox construction, toothing technology and the design of complete drive systems go into our rack and pinion systems.


  • Maximum movement speed and
    accelerationwith low moments of inertia
  • Excellent control characteristics due to constant
    linear rigidity along the entire movement path


  • Drive solutions with unique true running accuracy
  • Maximum positioning accuracy due to precisionalignment of components


  • Fast and easy assembly, e.g. with INIRA®
  • Effortless commissioning
  • Minimal mounting space and high power density
  • Huge savings potential
