The advantage of the internal circulation structure lies in the regular circular outer diameter of the screw, which makes the overall structure exquisite and compact, suitable for equipment with limited internal installation space. Attention should be paid during assembly: at least one end of the screw shaft of the internal circulation ball screw should be a fully threaded section, and the shoulder diameter of this end should be smaller than the outer diameter of the screw shaft, otherwise the nut cannot be assembled.
