Linear slider can be divided into three types: roller linear guide, cylindrical linear guide, and ball linear guide, which are used to support and guide the moving parts and make reciprocating linear motion in a given direction. Depending on the nature of friction, linear motion guides can be divided into sliding friction guides, rolling friction guides, elastic friction guides, fluid friction guides and other types.

It is divided into square ball linear guides, double-axis core roller linear guides, and single-axis core linear guides.
1. Linear guides are mainly used in automated machinery, such as machine tools imported from Germany, bending machines, laser welding machines, etc. Of course, linear guides and linear axes are matched.
2. Linear guides are mainly used in mechanical structures with relatively high precision requirements. There is no intermediate medium between the moving and fixed components of the linear guide, but rolling steel balls. Because the rolling steel ball is suitable for high-speed motion, has a small friction coefficient and high sensitivity, it can meet the working requirements of moving parts, such as the tool holder and carriage of the machine tool. If the force acting on the steel ball is too large, the steel ball will withstand the preload for too long, resulting in an increase in the movement resistance of the bracket.
