Abstract
A linear guide device includes at least one linear guide unit which has a guide housing, in which two annularly closed circulating channels are formed in each of which a multitude of roller bearing elements is received. The guide housing has a single-piece housing intermediate element which contributes to the formation of the circulating channels and through which passes at least one lubrication channel which communicates with the circulating channels. The lubrication channel passes through the single-piece housing intermediate element and extends partly also in an integral pipe-stub-like lubrication appendix of the single-piece housing intermediate element, wherein the lubrication appendix includes a lubrication opening which is accessible from outside the guide housing for bringing in lubricant.
