The role of linear guides

Definition: Linear guides, also known as line rails, slide rails, linear guides, linear slides, are used for linear reciprocating applications, and can withstand a certain amount of torque, enabling high-precision linear motion under high load conditions. Linear guides are called in the mainland. Taiwan is generally called linear guides and linear slides.


Classification: divided into square ball linear guide, double-axis core roller linear guide, single-axis linear guide.

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. Linear guides are mainly used on mechanical structures with high precision requirements. There is no intermediate medium between the moving parts and fixed elements of the linear guides, and rolling steel balls are used.
