How to choose ball screw bearings? zysbearing

 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, nut support, lock nut, etc. necessary for use have also been standardized and can be used by users.

The ball screw support bearing has high rotation accuracy, wide adaptability and easy installation and debugging. It is mainly used for the support of various precision ball screws and has a variety of structural forms to choose from:

Thrust angular contact ball bearings consist of a set of bearing units with integral inner and outer rings, steel balls and cage groups. The contact angle is 60°, and the axial rigidity is improved. DB (back-to-back), DF (face-to-face), DT (tandem) and Arrange freely.
