Ball screw assembly is consisted of screw, nut and balls. It isto transfer the rotary motion into linear motion or transfer thelinear motion into rotary motion.
Ball screw is widely used for all kinds of industrial equipmentsand precision instruments. Especially in recent years, it is widelyused in CNC machine tools ;

is made by grinding and whirling, (rolled steel processing isoption), and it has two kinds of ball screw, P for positioning andT for transmission, accuracy from 1 to 7, 1 is the highest and 7 isthe lowest;

Small mounting dimension in the radial and axial direction, easymounting, preload with single nut, small comprehesive tolerance, itis used to precision positioning with middle and light load,Notice: if clearance appears due to friction,there is no way totake preload normally.
