1. Basic structure of linear guide rail

直线导轨通常由导轨基座、导轨滑块和滑块密封件组成。导轨基座是导轨的固定部分，通常与设备的机架或壳体相连。导轨滑块是导轨的运动部分，可以在导轨上滑动，同时也可以承载运动部件的重量。滑块密封件主要用于防止尘埃和污垢进入滑块内部，从而保证导轨的精度和使用寿命。

A linear guide rail usually consists of a guide rail base, a guide rail slider, and a slider seal. The guide rail base is the fixed part of the guide rail, usually connected to the frame or shell of the equipment. The guide rail slider is the moving part of the guide rail, which can slide on the guide rail and also bear the weight of the moving parts. The slider seal is mainly used to prevent dust and dirt from entering the interior of the slider, thereby ensuring the accuracy and service life of the guide rail.
