1. Basic structure of linear guide rail

直線導軌通常由導軌基座、導軌滑塊和滑塊密封件組成。導軌基座是導軌的固定部分，通常與設備的機架或殼體相連。導軌滑塊是導軌的運動部分，可以在導軌上滑動，同時也可以承載運動部件的重量?；瑝K密封件主要用于防止塵埃和污垢進入滑塊內(nèi)部，從而保證導軌的精度和使用壽命。

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.
