Huge Torsional Rigidity
  • For the well-designed structure and high duty material of taper roller bearing, the output shaft of the reducer can bear the huge axial and radial load. The enlarged flange design could bear the biggest output torque and obtain the optimal rigidity, be proper on heavy machines.
High Dynamics
  • Planetary structure of balance, precision, and low inertia create high dynamics while collocating with servo motors.
High Positioning Accuracy
  • Precision ground gears have smooth surfaces and accurate profiles.
  • The series case and inner ring gear, designed into a one-piece structure, are made of special stable alloy steel.
Low Noise
  • For the high standard of ground gears and best-chosen synthetic oil.
  • For the professional gear producing experience and the serious quality control of manufacturing processes.
Easy Installation
  • For the modular input bushing and the changeable connecting plate according to the customer's brand of servo-motor.
Various output types
  • Standard, hollow, splined output shaft could be selected. Even customized output type.
Low gear backlash
  • Precision manufacture under quality control
  • Reduced backlash: stage one = 1-2 arcmins; stage two = 2-3 arcmins;stage three = 2-4 arcmins.
  • Standard backlash: stage one = 2-3 arcmins ; stage two = 3-4 arcmins; stage three = 4-7 arcmins.
  • Customization of further lower backlash is available.
Long Service Life and Easy Maintenance
  • The gear with the deep carburizing heat treatment and precision grinding process, make its high stiffness and mesh accurate, prolong the service life.
  • Best-chosen German synthetic oil lubricant and protect the components inside the gearbox, oil-filled free.
  • Select superior quality, heat-resistance, wear-resistance seal, get the better sealing performance.
