Linear guide device

A linear guide device with at least one linear guide unit which has a guide housing which extends in a housing longitudinal direction and which comprises two housing end sections which are distanced to one another in the housing longitudinal direction, in which guide housing at least two annularly closed circulating channels which are arranged adjacently to one another in a housing height direction which is at right angles to the housing longitudinal direction are formed, in which circulating channels a multitude of roller bearing elements is received, said roller bearing elements being rowed on one another in the channel longitudinal direction and being movable in the channel longitudinal direction whilst executing a circulating movement, wherein each circulating channel comprises two arcuate deflection channel sections which are each arranged in one of the two housing end sections and the guide housing has a single-piece housing intermediate element which comprises two intermediate element deflection sections which are each assigned to one of the two housing end sections and are each arranged between the deflection channel sections of the two circulating channels located in the same housing end section, wherein, on each of the sides of the housing intermediate element which are facing away from each another in the housing height direction, an inner wall surface section of one of the two assigned deflection channel sections is formed, wherein at least one lubrication channel which communicates with the circulating channels passes through the single-piece housing intermediate element of the guide housing of the linear guide unit and extends partly also in an integral pipe-stub-like lubrication appendix of the single-piece housing intermediate element, said lubrication appendix comprising a lubrication opening which is accessible from outside the guide housing for bringing in lubricant.
