Ball screw bearings can withstand large axial loads in a single direction, and can also withstand a certain radial load at the same time. Ball screw support bearings usually need to be used in double or multiple combinations, and the matching method is the same as angular contact ball bearings. ZYS ball screw bearing is a one-way angular contact thrust ball bearing with contact angle of 60°. It has good performance of high precision, high speed, high axial stiffness, low friction, long life and high&low speed transition conversion. ZYS ball screw bearing is particularly suitable for ball bearing lead screw and similar transmission components in high speed precision CNC machine tools. ZYS ball screw thrust bearings have 7602 and 7603 series, which are standard metric with internal diameters from 12mm to 130mm in accordance with JB/T8564 standard.  Email: sales@zys.com.cn Website: www.zys-bearing.com

Thin section bearings : The size of thin section bearings is different from common rolling bearings. Its cross-sectional size is generally in the range of 120.97 -645.16mm2, and the inner diameter is generally between 25.4mm to 1m. The inner diameter of common thin section bearings can also achieve 1.3m. Thin wall bearings are the thinnest in the size series. The inner diameter or outer diameter of bearing inner and outer rings are large, and the walls are thin. Its radial dimension of cross section is less than a quarter of the inner diameter and less than twice the diameter of the rolling element.For a certain series of dimensions, the cross-sectional dimension remains constant and has nothing to do with the inner diameter. For the common ball bearing series, the radial cross-section and the ball diameter generally increase with the increase of the inner diameter. Thin wall bearings also have tighter tolerances than common large and heavy-duty bearings. Therefore, thin wall bearings ...

 Ball screw bearings adapt to various purposes for bai, and du provides a wide range of standardized products. Widely used in machine tools, the ball circulation dao methods include circulating duct type, circulator type and end cap type. Preloading methods include positioning preloading (double nut method, position preloading method) and constant pressure preloading. The appropriate type can be selected according to the purpose. The screw has high-precision grinding precision ball screw (precision is divided into 6 grades from CO-C7) and cold-rolled ball screw bearing formed by high-precision cold rolling (precision is divided into 3 from C7-C10) Levels). In addition, in order to cope with the urgent need for delivery by users, there are finished products that have been processed on the end of the shaft, semi-finished products and cold rolled ball screw bearings that can be freely processed on the end of the shaft. As the peripheral parts of this bearing, the screw support unit, n...
