Overview of EPR Planetary Right Angle Gear Reducer

  • Low backlash, high rigidity, and high torque are the main characteristics of the PAR gear reducer.
  • The right-angle design of the reducer can efficiently save mounting space.
  • The elastic design of the connecting plate and the various sizes enables our gearbox to be combined with all brands of servo motors.
  • High-quality synthetic lubricants are used to make all parts in the gearbox fully lubricated and protected.
