Ball Screw

HANSAN/ISSOKU Precision Grinding Ball Screw Features and Benefits
HANSAN/ISSOKU Ball Screw, a true Korea ball screw for Korean market, was made with a traditional, 50-year-old gauge manufacturing technology and with the technological cooperation of Japan's ISSOKU Company and it is already recognized by small FA, robotics and semiconductor industries for its outstanding quality.
Also, all the screw and nut products are made with the company’s excellent screw processing technologies and lapping method and they are quiet and durable with much smoother rolling motion than any other ground screws.
