In order to adapt to various purposes, ball screw bearings provide a wide range of standardized products. Widely used in machine tools, the ball circulation 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 delivery of users, there are finished products that have been processed on the shaft ends, semi-finished products and cold rolled ball screw bearings that can be freely processed on the shaft ends. 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.
