What is the function of precision linear rails?

The role of precision linear rails
The role of precision linear rails is to support and guide moving parts, making reciprocating linear motion in a given direction. According to the friction properties, precision linear rails can be divided into sliding friction guides, rolling friction guides, elastic friction guides, fluid friction guides and so on. 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 precision linear rails, which are mainly used on mechanical structures with high precision requirements, there is no need for intermediate media between moving parts and fixed elements of linear guides, but rolling steel balls.

Precision linear rails
The DF (45-°45)° combination from the circular groove can be absorbed by the elasticity of the steel ball and the transfer of the contact point during the installation, even if the mounting surface is somewhat deviated, it can be absorbed by the inside of the line slider. The effect of automatic self-aligning ability is produced to obtain a smooth motion with high precision and stability.

Precision linear rails are interchangeable
Due to the strict control of production precision, the precision linear rails can be kept at a certain level, and the slider has a retainer design to prevent the steel balls from falling off. Therefore, some series of precisions are interchangeable, and customers can order the guides as needed. Or sliders, you can also store the rails and sliders separately to reduce storage space.Precision linear rails have high rigidity in all directions
The four-row circular groove is matched with the contact angle of 45 degrees such as four rows of steel balls to make the steel ball reach the ideal two-point contact structure, which can withstand the load from the up and down and the left and right directions; if necessary, it can apply preload to improve rigidity.

Application areas of precision linear rails
1. Precision linear rails are mainly used in automation machinery, such as machine tools imported from Germany, bending machines, laser welding machines, etc. Of course, linear guides and linear axes are used.2, precision linear rails are mainly used in mechanical structures with high precision requirements. Precision linear rails use rolling media instead of intermediate media between moving components and fixed components. Because the rolling steel ball is suitable for high-speed movement, small friction coefficient and high sensitivity, it can meet the working requirements of moving parts, such as tool holders and carriages of machine tools. If the force acting on the steel ball is too large, the steel ball is subjected to the preloading time for too long, resulting in an increase in the kinematic resistance of the bracket.
