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!

這主要從外觀上區別，圓軌從外觀上看是圓形的，直線導軌又稱方軌，外觀上是長方體的。

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、直線導軌產品特點定位精度高，重現性佳直線導軌的滾動運動方式，摩擦系數比較小，靜摩擦力與動摩擦力的差距很小，即使在進給時也不會有空轉打滑的現象，解析能力與重現性較好，因此可以實現木工雕刻機可長時間維持精度直線導軌的滾動摩擦力μm級的定位精度。低摩擦阻力。潤滑容易，可減小滑動導軌摩擦阻力的1/20~1/40潤滑結構簡單。摩擦接觸面的磨耗降底，滑作用優良。因此可以長時間維持行走精度。

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、從摩擦、可承受載負荷考慮，方規就是方型直線導軌是面接觸式摩擦，摩擦力較大，負載均勻，需要經常上油潤滑但圓形導軌就是圓柱形的線型導軌，摩擦小，由于是一系列滾珠的點接觸，需要支撐的地方有限，剛性差，負載性能有限，載徑向有較好承載力，軸向承載比較小。而且方形軌道高速，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.
