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.

直線導軌的潤滑方式根據客戶需要在滑塊前端或者后端裝上油嘴以供手動打油，RG系列特別在端蓋側面與上面均預留油孔位置以安裝油嘴（一般為直油嘴），提供側向與上方打油。

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.

側向打油的位置建議在非側基準邊，但若有特殊需要也可以放在側基準面旁?？蛻羧粲猩鲜鰝认虼蛴突蛘呱戏酱蛴托枨?，我們也可以讓我們的工程師來通過設計不同的方案來解決這種問題。同時也可以根據以下幾個方面來確定。

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.

如果客戶的工作環境在相對污染的情況下，那么我們盡量把打油的油孔安裝到直線導軌的外側來實現，這樣避免進了臟東西導致直線導軌滑動起來不順暢。還有一種情況就是不是很污染的環境，我們也可以在直線導軌的上面打油孔來實現。盡量安裝使用手動打油的那種的也好，這樣可以增加直線導軌滑動的順暢度。

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.

總之，直線導軌的潤滑方式有很多種，我們可以根據客戶的要求來隨時隨位置進行安裝。

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.
