1. Linear guide rails are mainly used in automatic machines, such as machine tools imported from Germany, paper bowl machines, laser welding machines, etc. Of course, linear guide rails and linear shafts are used in a matching way.

2. The linear guide rail is mainly used in mechanical structures with high precision requirements. No intermediate medium is used between the moving element and the fixed element of the linear guide rail, but rolling steel balls are used. Because 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 rest and carriage of machine tools. If the force acting on the steel ball is too large, the steel ball will be subjected to preload for too long, resulting in an increase in the movement resistance of the support.
