The function of the linear guide is to support and guide the moving parts, and to do reciprocating linear motion in a given direction. Depending on the nature of massage friction, linear motion guides can be divided into sliding friction guides, rolling friction guides, elastic friction guides, fluid friction guides and other types. Linear bearings are mainly used in automated machinery, such as machine tools imported from Germany, bending machines, laser welding machines, etc. Of course, linear bearings and straight shafts are used together. Like linear guides are mainly used in mechanical structures with high precision requirements!
Due to the strict control of manufacturing accuracy, the size of the linear guide can be maintained within a certain level, and the slider is designed with a sticker to prevent steel balls from falling off, so some series of precision are interchangeable. Customers can order guide rails or sliders according to their needs, and can also store guide rails and sliders separately to reduce storage space.
The DF (45- ° 45) ° combination from the arc groove, during installation, by the elastic deformation of the steel ball and the transfer of the contact point, even if the installation surface is somewhat inclined, it can be absorbed by the inside of the line rail slider, resulting in the effect of automatic centering and high-precision and stable smooth movement. The use of four-row arc grooves, with four rows of steel balls and other 45-degree contact angles, allows the steel ball to reach the ideal two-point contact structure, which can withstand the load from the up and down and left and right directions; when necessary, pre-pressure can be applied to improve rigidity.
