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