Ball screw bearing

Ball screw bearings are used in ball screw bearings, ball screws are commonly used in tool machinery and precision machinery transmission elements, without bearings, these precision machinery is impossible to operate. Because of its small friction resistance, it is widely used in all kinds of industrial equipment and precision instruments.


Ball screw bearing is used in ball screw. Ball screw is a common transmission element in tool machinery and precision machine. Its main function is to convert rotating motion into linear motion, or torque into axial repeated force, at the same time, it has high precision, reversibility and high rate. Ball screw is composed of screw, nut, steel ball, prepress, backward device and dust preventer. Its function is to transform the rotation motion into straight line motion, which is the progress, extension and development of Ekham screw. The important significance of this development is to change the bearing from sliding action to rolling action. It is widely used in machine tools, and The circulation mode of ball is circulation guide pipe, circulator type and cover type. Preloading mode has positioning preloading (double nut mode, position preloading mode), constant pressure preloading.
