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, the guide housing comprising:

• two housing end sections which are distanced to one another in the housing longitudinal direction;
• at least two annularly closed circulating channels formed in the guide housing, the circulating channels being arranged adjacently to one another in a housing height direction which is at a right angle to the housing longitudinal direction;
• a multitude of roller bearing elements received in each of the circulating channels, said roller bearing elements being arranged in rows in the channel longitudinal direction and being movable in the channel longitudinal direction whilst executing a circulating movement;
• and
• a single-piece housing intermediate element, the housing intermediate element having a top side and a bottom side facing away from each other in the height direction, the housing intermediate element further including two intermediate element deflection sections and at least one integral lubrication pipe appendix having a lubrication opening which is accessible from outside the guide housing for bringing in lubricant,
• wherein each circulating channel comprises two arcuate deflection channel sections which are each arranged in one of the two housing end sections, and
• wherein each intermediate element deflection section of the housing intermediate element is arranged between the deflection channel sections of the two circulating channels located in the same housing end section, and
• wherein an inner wall surface section of one of the two respective deflection channel sections is formed on each of the top side and the bottom side of the housing intermediate section, and
• wherein at least one lubrication channel which communicates with the circulating channels passes through the housing intermediate element and extends partly in the lubrication pipe appendix of the housing intermediate element.
