Linear guides are mainly composed of sliders and guides, and the sliders are mainly used for sliding friction guides. They are used for linear reciprocating motion, and can bear a certain torque, and can achieve high-precision linear motion under high load.

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. Linear guideway are mainly used in automated machineries, such as machine tools , bending machines, laser welding machines, etc.Linear guides are mainly used in mechanical structures that require relatively high precision. 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.
