I tried to make a coupling by myself to join DC motors, but as the centering did not go well, I bought this product. There is neither vibration nor shake, it is in good condition. The electric motor of this time fitted with the diameter of the rotor shaft about 11 mm and had a key groove in the shaft, so it was possible to fix it well with the setscrew. The DC motor is SANYO DENKI CO. LTD DC SERVO MOTOR R 720 - 039 W 65 W 30 V 3.6 A 1050 min - 1.
