Price Guide: POA


  • Standards gears which are designed according to ISO 6336.
  • The output housing is made of nodular cast iron and designed to hold the heavy loads generated during the machine’s job.
  • The gears are made of alloyed steel and are heat treated (case hardening for suns and planets, induction hardening or nitriding for internal toothed rings).
  • The planets are supported by roller bearings or full rollers track bearings to obtain a high efficiency during the phases of starting and running.
  • There can be 3 to 5 reduction stages (all of them with a planetary design), depending upon the total required reduction ratio.
  • Each stage may have 3 to 4 planets (to increase the deliverable torque).


  • High torque capacity.
  • High radial/thrust load capacity.
  • High shock resistance and designed for heavy duty.
  • Wide range of reduction ratios (from 60 up to 3000).
  • Compact dimensions.


  • Wind turbines.
