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.
