There are significant differences between rectangular sliding guide rail and linear guide rail in many aspects，These differences are mainly structural、property、Application scenario and maintenance difficulty。

one、Structural difference

• Rectangular slide guide：It is usually composed of a guide rail and a guide slide，Its structural design is simple and clear，The four sides are equidistant，Rectangular in section。This design makes the rectangular guide rails have high stiffness and load capacity，Can effectively distribute the load。

• Linear guide：Also known as the slide rail、Linear guide rail or linear slide rail，The movement is mainly achieved by rolling the ball or roller between the slider and the track。Its structure is relatively complex，But it can achieve high precision linear motion。

two、Performance characteristics

• Rectangular slide guide：

• High stiffness：Because its four sides are equidistant、Structural design of rectangular section，Rectangular guide rails have high stiffness，Able to withstand large loads。

• High precision：Precision machined and calibrated，Rectangular guide rails ensure the stability and accuracy of the transmission system。

• Long life：High quality materials and processing techniques are used，Rectangular guide rails have a long service life，It can operate stably in harsh environments for a long time。

• Strong carrying capacity：The design structure can effectively distribute the load，Increase carrying capacity。

• Wide range of application：Suitable for all kinds of motion control systems，Such as CNC machine tools、Automatic assembly line、robot。

• Linear guide：

• Low friction resistance：Because of the point contact，The friction resistance of linear guide rail is very small，Capable of subtle movements，Suitable for high precision positioning。

• Allowable load：The rolling groove of the ball or roller distributes the force，Therefore, there is a larger allowable load。

• High motion accuracy：In the same moving component volume，Linear guide rails have higher rated load and motion accuracy than linear bearings。

• Suitable for high speed movement：Not easy to generate friction heat，Not susceptible to heat deformation，Therefore, it is suitable for high-speed motion scenes。

three、Application scenario

• Rectangular slide guide：Due to its high stiffness、High precision and strong bearing capacity，Rectangular guides are more suitable for large machine tools and automation equipment that require large loads and precise control。

• Linear guide：Because of its low friction resistance、Allowable load、High precision and suitable for high-speed movement，Widely used in machine tools、Electronic appliance、Medical treatment、Robotics and other industries，Especially those with high accuracy and speed requirements。

four、Maintenance difficulty

• Rectangular slide guide：Once damaged，Because of its structural characteristics，May be more difficult to repair，And requires more surface preparation work。

• Linear guide：Relatively speaking，Linear guide rail maintenance is relatively simple，And less surface preparation is required for assembly。

To sum up，Rectangular sliding guide rail and linear guide rail in the structure、property、There are significant differences in application scenarios and maintenance difficulty。At the choice，Comprehensive consideration should be made based on specific application scenarios and requirements。
