The function of the linear guide is to support and guide the moving parts, and to perform reciprocating linear motion in a given direction. In order to apply the right type of linear guide to the right situation, it is necessary for the design engineer to understand the advantages and capabilities of different guides, so as to make a reasonable choice.

It is used in conjunction with linear bearings and linear shafts. It is cylindrical in appearance and can be assembled with circular holes. At the same time, the linear bearing can also be used with the slider to achieve plane installation. The installation and use of the circular guide rail are more convenient and save space. It is used in conjunction with a square slider and a square guide rail, which is square in appearance. Considering the friction and load, the square guide rail is the surface contact friction between the guide rail and the slider, the friction force is large, the load is uniform, and it needs to be lubricated frequently.

For the choice of circular guide rail and square guide rail, mainly from the load, accuracy, stiffness, finish and other factors to consider. The typical application of square guide rail is the machine tool industry with high requirements for load capacity, stiffness and accuracy. However, after meeting the above conditions, it is difficult to meet other requirements, such as high installation requirements, high upfront costs, and high maintenance costs. The circular guide rail in this regard reflects its advantages when installed on the flatness of the less smooth surface, still able to run smoothly. Round rails are generally more quickly installed and run more smoothly than square rails.
