Precision PlanetGear - PSC

The demand for high-precision gears in mechanical engineering and system building is constantly on the rise. Requirements include low backlash and high torques while taking into account optimal values for tipping and backlash stiffness, all in the most compact design possible.

  • 7 sizes in two- or three-stage design
  • Ratios from 71:1 to 200:1
  • Acceleration torque up to 4500Nm
  • High efficiency up to 95% 
  • High torsional stiffness and tilting rigidity
  • Reduced backlash <0,6arcmin
  • High positioning accuracy 
  • The better controllability of the entire system is ensured through the low breakaway torque
  • The low mass moment of inertia enable an optimum dynamic response
  • Compact construction
  • Low running noise and low heat development
