Ratio 25 ~ 4,000
Input power 0.4~9551 KW
Output torque 22~1920 kN.m


P series planetary gearboxes uses several planet gears to transfer load, thus to actualize power division and effective use of inner engagement. It is featured by compact structure, small volume, lightweight, wide range of ratio, high driving efficiency, etc.


  • Modular design, variable combination with other Series as required
  • Housing material: nodular cast iron, better rigidity and better anti-vibration capability.
  • Carburize-hardening of sun, planet, pinion and bevel gears to achieve high rigidity and good wear resistance, all teeth ground after heat treatment, thus noise reduced and the gear units efficiency and lifetime enhanced.
  •  Input Mode: Coaxial input, helical gear input, bevel-helical gear input.
  • Output mode: Internal involute spline, hollow shaft with shrink disk, external involute spline, solid shaft with flat key.
  • Mounting mode: Horizontal vertical, torque-arm.
  • P series size:9~34, transmission stage:2 stage and 3 stage, Ratio:25~4000, ratio will be larger in combination with K,R, series.
