直線導軌又稱精密滾動直線導軌副、滑軌、線性導軌、線性滑軌、滾動導軌，用于高進度的平行度的直線往復運動場合，額定負載比直線軸承高，有一定的扭矩，高負載仍能高精度的直線運動。

Linear guide rail, also known as precision rolling linear guide rail pair, slide rail, linear guide rail, linear guide rail, rolling guide rail, is used for high-precision parallel linear reciprocating motion occasions. The rated load is higher than linear bearings, and there is a certain amount of torque. High load can still achieve high-precision linear motion.

直線運動導軌可以分為滑動摩擦導軌、滾動摩擦導軌、彈性摩擦導軌、流體摩擦導軌等種類，廣泛應用于精度較高的數控機床。線軌是利用滾柱（雙排）在導軌側面滑槽里滑動，屬于滾動導軌副。

Linear motion guideway can be divided into Sliding friction guideway, rolling friction guideway, elastic friction guideway, fluid friction guideway and other types, which are widely used in CNC machine tools with high accuracy. The track is a rolling guide pair that uses rollers (double rows) to slide in the side grooves of the guide rail.

導軌絲杠廠家再來講講靜壓導軌：

The manufacturer of the guide screw will talk about the hydrostatic guide rail again:

自身結構比較復雜，并有一套供油系統。在搗鬼的接觸面注入一定的導軌油并形成承載油膜，使導軌與滑塊的運動之間處于純液體摩擦狀態。這對潤滑油的清潔程度要求很高。

It has a relatively complex structure and a set of oil supply systems. Inject a certain amount of guide rail oil into the contact surface of the troublemaker and form a load-bearing oil film, so that the movement between the guide rail and the slider is in a pure liquid friction state. This requires a high level of cleanliness for the lubricating oil.

靜壓導軌導軌和滑塊之間的油膜是通過壓力形成，使滑塊有0.02-0.03mm的浮起，滑塊和導軌之間的摩擦系數就大大減小了，但其依然屬于滑動導軌副。

The oil film between the hydrostatic guide rail and the slider is formed by pressure, causing the slider to float 0.02-0.03mm, greatly reducing the friction coefficient between the slider and the guide rail, but it still belongs to the sliding guide rail pair.

采用的是硬軌的靜壓導軌當出現磨損或劃痕時很難進行修正，而線軌可以隨時更換。同時，靜壓導軌因為制造工藝更復雜，比直線導軌要高。

The static pressure guide rail using hard rails is difficult to correct when worn or scratched, while the track can be replaced at any time. Meanwhile, due to the more complex manufacturing process, the price of static pressure guide rail is higher than that of linear guide rail.
