As a professional rolling functional unit manufacturer in China, we can provide ball screw and straight line guide to our clients. The ball screw is mainly used to transform rotational motion to linear motion with little friction. And it can be used to move control surfaces in aircraft and missiles, especially for electric fly by wire. Besides, it is also suitable for machine tools, robots, and precision assembly equipment. Since ball screws are equipped with a special mechanism to re-circulate the balls, they are bulkier than conventional lead screws. The straight line guide features high efficiency, low energy consumption, low running cost, high precision, low frictional resistance and long service life, etc. We can provide RIT-LA, RIT-LB, RIT-LC and RIT-LR heavy-duty straight line guides for customers to choose. They are designed with lengthened slide block and more effective balls, thus possessing higher rated load and rigidity. Established in 1954, Jiangsu Right Machinery Group Co., Ltd mainly provides two kinds of rolling functional units: ball screw and straight line guide.
