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。
