Linear guide rails and are very important mechanical accessories around us. Do you know the difference between them? Let's get to know each other today!

这主要从外观上区别，圆轨从外观上看是圆形的，直线导轨又称方轨，外观上是长方体的。

This is mainly different from the appearance. The circular rail is circular in appearance, and the linear rail is also called square rail, which is rectangular in appearance.

1、直线导轨产品特点定位精度高，重现性佳直线导轨的滚动运动方式，摩擦系数比较小，静摩擦力与动摩擦力的差距很小，即使在进给时也不会有空转打滑的现象，解析能力与重现性较好，因此可以实现木工雕刻机可长时间维持精度直线导轨的滚动摩擦力μm级的定位精度。低摩擦阻力。润滑容易，可减小滑动导轨摩擦阻力的1/20~1/40润滑结构简单。摩擦接触面的磨耗降底，滑作用优良。因此可以长时间维持行走精度。

1. Linear guide rail product features high positioning accuracy and good reproducibility. The rolling motion mode of linear guide rail has a relatively small friction coefficient, and the difference between static friction and dynamic friction is very small. Even when feeding, there will be no idling and slipping, and the analysis ability and reproducibility are good. Therefore, the woodworking engraving machine can maintain the rolling friction of precision linear guide rail for a long time μ M level positioning accuracy. Low friction resistance. It is easy to lubricate and can be reduced to 1/20~1/40 of the friction resistance of the sliding guide rail. The lubrication structure is simple. The friction contact surface is worn to lower the bottom and has excellent sliding effect. Therefore, the walking accuracy can be maintained for a long time.

2、从摩擦、可承受载负荷考虑，方规就是方型直线导轨是面接触式摩擦，摩擦力较大，负载均匀，需要经常上油润滑但圆形导轨就是圆柱形的线型导轨，摩擦小，由于是一系列滚珠的点接触，需要支撑的地方有限，刚性差，负载性能有限，载径向有较好承载力，轴向承载比较小。而且方形轨道高速，阻力小。

2. Considering the friction and load bearing capacity, the square gauge refers to the square linear guide rail, which is a surface contact friction with large friction and uniform load, and needs to be lubricated frequently. However, the circular guide rail is a cylindrical linear guide rail with small friction. Due to the point contact of a series of balls, the places to be supported are limited, the rigidity is poor, the load performance is limited, the radial bearing capacity is good, and the axial bearing capacity is relatively small. Moreover, the square track is of high speed and low resistance.
