Self lubricating linear guide rail

Self lubricating linear guide with lubrication mechanism between the end cover and oil scraper, and a detachable oil tank at the outermost end of the slider. Lubricating oil is provided to the lubrication mechanism through a detachable oil tank, and the guide rail bead groove is lubricated by the lubrication mechanism. The oil tank contains an oil guide element, whose specific three-dimensional shape allows the slider to come into contact with lubricating oil at any position or when the oil volume is low, and completely suck out the lubricating oil in the oil tank for use.
