Double Nut Dfi Type Ball Screw

Ball screw is the ideal product for converting rotary motion into linear motion, or converting linear motion into rotary motion.

Ball screw is the most commonly used transmission component in tool machinery and precision machinery. Its main function is to convert rotary motion into linear motion, or to convert torque into axial repeated force. At the equal time, it has the traits of high precision, reversibility and high efficiency. Because of its low friction resistance, ball screws are widely used in various industrial gear and precision instruments.

Ball screw is composed of screw, nut, steel ball, preloaded sheet, reverse device and dustproof device. Its function is to convert rotating motion into linear motion, which is the further extension and development of Acme screw. The important significance of this development is to change the bearing from sliding action to rolling action.

Product Details

Ball screw bearings provide a wide variety of standardized merchandise to adapt to pretty a quantity uses. Widely used in machine tools, the circulation mode of ball bearing has circulating catheter type, circulator type, quit cap type. Preloading modes consist of positioning preloading (double nut preloading, bit preloading) and steady preloading. The appropriate type can be selected according to the purpose. The lead screw has precision ball screw with high precision grinding (precision is divided into 6 grades from CO-C7) and cold-rolled ball screw bearing with high precision machining (precision is divided into 3 grades from C7-C10). In addition, in order to meet the pressing delivery situation of users, there are finished merchandise which have been processed on the shaft end, semi-finished products which can be freely processed on the shaft quit and cold rolled ball screw bearings. As the peripheral components of this bearing, the necessary lead screw information units, nut supports, locking nuts and so on have also been standardized for customers to pick out to use.
