直线导轨又称精密滚动直线导轨副、滑轨、线性导轨、线性滑轨、滚动导轨，用于高进度的平行度的直线往复运动场合，额定负载比直线轴承高，有一定的扭矩，高负载仍能高精度的直线运动。

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.

直线运动导轨可以分为滑动摩擦导轨、滚动摩擦导轨、弹性摩擦导轨、流体摩擦导轨等种类，广泛应用于精度较高的数控机床。线轨是利用滚柱（双排）在导轨侧面滑槽里滑动，属于滚动导轨副。

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.

导轨丝杠厂家再来讲讲静压导轨：

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

自身结构比较复杂，并有一套供油系统。在捣鬼的接触面注入一定的导轨油并形成承载油膜，使导轨与滑块的运动之间处于纯液体摩擦状态。这对润滑油的清洁程度要求很高。

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.

静压导轨导轨和滑块之间的油膜是通过压力形成，使滑块有0.02-0.03mm的浮起，滑块和导轨之间的摩擦系数就大大减小了，但其依然属于滑动导轨副。

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.

采用的是硬轨的静压导轨当出现磨损或划痕时很难进行修正，而线轨可以随时更换。同时，静压导轨因为制造工艺更复杂，比直线导轨要高。

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.
