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

1、注意导轨防尘：如果粉尘及其他异物进入直线导轨系统，将导致异常磨损，并缩短使用寿命，因而需要防止异物进入系统。所以预计可能会有粉尘及其他异物进入时，有必要选择满足使用环境条件句的密封装置或粉尘装置，直线导轨根据型号提供滑块的防尘保护附件。

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、定期清洁防锈：防锈工作要确定材料，针对不同材料的直线导轨作不同的维护项，直线导轨有必要选 择能够满足使用环境要求的材质；然后要注意直线导轨表面处理，直线导轨和轴的表面可以进行防锈处理。

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、定期添加润滑油：直线导轨作为零部件，经常重复直线运动来回运动，而润滑剂保证了机械工作的流畅性 ，因此导轨拥有良好的润滑功能。如果润滑效果差，在长时间，摩擦大的条件下工作，会使滚动部分就会更快地磨损，因而其使用寿命会缩短。日常维护工作，能够使直线导轨在使用过程中，具有较高的导向精度和良好的运动平稳性。

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.
