1. Linear guides are mainly used in automation machinery, such as machine tools imported from Germany, bending machines, laser welding machines, etc. Of course, linear guides and linear axes are used.
2. The linear guide rail is mainly used on the mechanical structure with high precision requirements. The intermediate medium is not used between the moving component and the fixed component of the linear guide rail, and the rolling steel ball is used. Because the rolling steel ball is suitable for high-speed movement, small friction coefficient and high sensitivity, it can meet the working requirements of moving parts, such as tool holders and carriages of machine tools. If the force acting on the steel ball is too large, the steel ball is subjected to the preloading time for too long, resulting in an increase in the kinematic resistance of the bracket.
