A slideway guide unit for column ways in toolmaking and machine construction comprises a guide unit and a sliding element, secured to it and in contact with a guideway, together with a lubricating device for lubricating the guideway. The invention prevents lubricant losses during assembly and disassembly operations. The sliding element is connected to the guide unit in a positive, impervious and detachable manner, using intermediate sealing elements. The lubricating device displays at least one integrally molded, annular lubricant chamber in the region of the outer wall of the sliding element. At least one of the lubricant chambers is provided with an inlet and each of the lubricant chambers has at least one self-closing outlet for a lubricant, and the outlets penetrate the sliding element and end on the guideway.
