Equipped with the domestic top-brand planetary gear reducer, it can reach a back clearance of 0.05°, realizing features of high precision of servo motor in max. extend. High-precision linear guide ways are adopted, featuring better abrasive resistance,longer service life, faster speed and lower noise. The internationally renowned brand of synchronous belts are used, which have better abrasive resistance,lower noise,longer serice life, better anti-corosion property and oll resistance. The adoption of  extracion axs for the transmission of helical gears and heringbone gears boasts a simple structure and faster response.
