There are many lubrication methods for linear guide rail. Each brand has different lubrication methods. This can be installed in different positions according to customer requirements. The same brand may have different installation methods, but their general requirements are generally the same.

直线导轨的润滑方式根据客户需要在滑块前端或者后端装上油嘴以供手动打油，RG系列特别在端盖侧面与上面均预留油孔位置以安装油嘴（一般为直油嘴），提供侧向与上方打油。

The lubrication mode of the linear guide rail is to install an oil nozzle at the front or rear end of the slider according to the customer's needs for manual oil pumping. RG series especially reserves oil holes on the side and above the end cover to install the oil nozzle (generally straight oil nozzle) to provide lateral and upper oil pumping.

侧向打油的位置建议在非侧基准边，但若有特殊需要也可以放在侧基准面旁。客户若有上述侧向打油或者上方打油需求，我们也可以让我们的工程师来通过设计不同的方案来解决这种问题。同时也可以根据以下几个方面来确定。

The position of lateral oiling is recommended to be on the non side datum side, but it can also be placed next to the side datum plane if there are special needs. If the customer has the above demand for lateral or upper oiling, we can also ask our engineers to solve this problem by designing different solutions. At the same time, it can also be determined according to the following aspects.

如果客户的工作环境在相对污染的情况下，那么我们尽量把打油的油孔安装到直线导轨的外侧来实现，这样避免进了脏东西导致直线导轨滑动起来不顺畅。还有一种情况就是不是很污染的环境，我们也可以在直线导轨的上面打油孔来实现。尽量安装使用手动打油的那种的也好，这样可以增加直线导轨滑动的顺畅度。

If the customer's working environment is relatively polluted, we try to install the oil hole for oiling on the outside of the linear guide rail, so as to avoid that the linear guide rail does not slide smoothly due to dirt. Another situation is that the environment is not very polluted. We can also drill oil holes on the linear guide rail. Try to install the manual oiling one, which can increase the smoothness of linear guide rail sliding.

总之，直线导轨的润滑方式有很多种，我们可以根据客户的要求来随时随位置进行安装。

In short, there are many ways to lubricate the linear guide rail. We can install it at any time according to the customer's requirements.
