The daily maintenance of linear guide rail mainly includes the following three aspects:

1、注意導軌防塵：如果粉塵及其他異物進入直線導軌系統，將導致異常磨損，并縮短使用壽命，因而需要防止異物進入系統。所以預計可能會有粉塵及其他異物進入時，有必要選擇滿足使用環境條件句的密封裝置或粉塵裝置，直線導軌根據型號提供滑塊的防塵保護附件。

1. Pay attention to the dust prevention of guide rail: if dust and other foreign matters enter the linear guide rail system, they will cause abnormal wear and shorten the service life. Therefore, it is necessary to prevent foreign matters from entering the system. Therefore, when it is expected that dust and other foreign matters may enter, it is necessary to select the sealing device or dust device that meets the service environmental conditions. The linear guide rail provides the dust protection accessories of the sliding block according to the model.

2、定期清潔防銹：防銹工作要確定材料，針對不同材料的直線導軌作不同的維護項，直線導軌有必要選 擇能夠滿足使用環境要求的材質；然后要注意直線導軌表面處理，直線導軌和軸的表面可以進行防銹處理。

2. Regular cleaning and rust prevention: the rust prevention work should first determine the materials, and make different maintenance items for the linear guide rail of different materials. It is necessary to select the materials that can meet the requirements of the use environment; Then pay attention to the surface treatment of linear guide rail. The surfaces of linear guide rail and shaft can be treated with rust prevention.

3、定期添加潤滑油：直線導軌作為零部件，經常重復直線運動來回運動，而潤滑劑保證了機械工作的流暢性 ，因此導軌擁有良好的潤滑功能。如果潤滑效果差，在長時間，摩擦大的條件下工作，會使滾動部分就會更快地磨損，因而其使用壽命會縮短。日常維護工作，能夠使直線導軌在使用過程中，具有較高的導向精度和良好的運動平穩性。

3. Add lubricating oil regularly: as a component, the linear guide rail often repeats the linear movement back and forth, and the lubricant ensures the smoothness of mechanical work, so the guide rail has good lubrication function. If the lubrication effect is poor, working under the condition of long time and high friction will make the rolling part wear faster, so its service life will be shortened. The daily maintenance work can make the linear guide rail have high guiding accuracy and good motion stability in the process of use.
