 NN120F  REDUCER (Gearbox)
NN60 Reducer
NN60 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。
