 NN90  REDUCER (Gearbox)
NN90 Reducer
NN90 Reducer
      CUKEN Technical the latest launch stepper motor/servo motor series precision reducer, which using planetary transmission designed,superior product characteristics:
  • The structure is compact,with the smallest size of the existing models reducer(Gearbox);
  • More teeth、average load,gear meshing with the low-speed transmission;
  • Large Torque Transfer,Broad Ratio Scope;
  • High efficiency ,Large radial-carrying capacity;
  • Backlash small gap,the transfer of high precision;
  • Installation is simple,coaxial output;
  • Little fever;Low noise;Longevity;Low prices。
                          
  • Attention: We can provide the reducer of 5-10000 deceleration ratios according to customer's need.
