Linear guides are also called line rails, slide rails, linear guides, and linear slide rails. It is used for linear reciprocating motion and can withstand a certain torque to achieve high-precision linear motion under high load. China is called a linear guide. Taiwan is generally called linear guides and linear slides.
It is divided into square ball linear guide, double shaft core roller linear guide, single axis core linear guide.
Linear Guides role
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 and so on. Of course, linear bearings and linear shafts are used together. Linear guides are mainly used on mechanical structures with high precision requirements. Instead of an intermediate medium between the moving element and the fixed element of the linear guide, a rolling steel ball is used.
Linear guide automatic self-aligning ability
The combination of DF (45-°45)° from the circular groove, at the time of installation, is the elastic deformation of the steel ball and the transfer of the contact point. Even if the mounting surface is somewhat deviated, it can be absorbed by the inside of the line slider, resulting in the effect of self-aligning ability and smooth motion with high precision and stability.
Linear guides are interchangeable
Due to the strict control of production and manufacturing precision, the size of the linear guide can be maintained within a certain level, and the slider has a retainer design to prevent the steel ball from falling off. Therefore, some series of precisions are interchangeable. Customers can order rails or sliders as needed. Separate storage rails and sliders to reduce storage space.
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 and can withstand the load from the up and down and left and right directions;
Preloading can be applied as necessary to increase rigidity.
1. Linear guides 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 together.
2. Linear guides are mainly used on mechanical structures with high precision requirements. Instead of an intermediate medium between the moving element and the fixed element of the linear guide, a rolling steel ball is used. 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.
- For the outer wheel separation type and the inner wheel rotation.
- For use where it is necessary to rotate the inner wheel.
