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


The function of the linear guide motion is to support and guide the moving parts to make a reciprocating linear motion in a given direction. Depending on the nature of the friction, linear motion guides can be classified into sliding friction guides, rolling friction guides, elastic friction guides, and fluid friction guides. Linear bearings are mainly used in automation machinery, such as machine tools imported from Germany, bending machines, laser welding machines, etc. Of course, linear bearings and linear shafts are used together. Like a linear guide, it is mainly used on a mechanical structure with high precision requirements. The intermediate member is not used between the moving member and the fixed member of the linear guide, and the rolling steel ball is used.
