• wherein the roller running track surfaces (6, 7) of the profile guide rail (5) and the roller running track surfaces (20, 21) of the main body (11) are arranged relative to each other in such a way that one of the roller running track surfaces (6;
• 7) of the profile guide rail (5) and one of the roller running track surfaces (20;
• 21) of the main body (11) extend parallel to each other and are arranged opposite to each other at a distance from each other in such a way that the respective one of the roller running track surfaces (6;
• 7) of the profile guide rail (5) and the respective one of the roller running track surfaces (20;
• 21) of the main body (11) delimit a load-bearing roller passage channel (LK1, LK2);
• wherein the guide carriage (10)-for each of the load-bearing roller passage channels (LK1, LK2)-each comprises a full complement roller deflection device (UV1, UV2) for a plurality of rows (RR1, RR2) of rollers (R1, R2) arranged next to each other, the roller deflection device being assigned to the respective individual of the load-bearing roller passage channels (LK1, LK2), wherein the roller deflection device (UV1, UV2) is attached to the main body (11) and comprises a roller circulation channel (UK1, UK2) extending in a ring-shaped manner, wherein the roller circulation channel (UK1, UK2) defines a ring-shaped closed roller orbit for the plurality of rows (RR1, RR2) of rollers (R1, R2) arranged next to each other,
• wherein the roller circulation channel (UK1, UK2) of the roller deflection device (UV1, UV2) comprises:
• a first section (UK1-1, UK2-1) of the roller circulation channel (UK1, UK2), which is identical to the respective one of the load-bearing roller passage channels (LK1, LK2),
• a second section (UK1-2, UK2-2) of the roller circulation channel (UK1, UK2), which extends at a distance from the first section (UK1-1, UK2-1) of the roller circulation channel in the longitudinal direction of the profile guide rail,
• a third section and a fourth section (UK1-3, UK2-3, UK1-4, UK2-4) of the roller circulation channel (UK1, UK2), wherein the third section (UK1-3, UK2-3) of the roller circulation channel (UK1, UK2) connects one of two opposite ends of the first section (UK1-1, UK2-1) of the roller circulation channel (UK1, UK2) to one of two opposite ends of the second section (UK1-2, UK2-2) of the roller circulation channel (UK1, UK2), and the fourth section (UK1-4, UK2-4) of the roller circulation channel connects the other one of the two opposite ends of the first section (UK1-1, UK2-1) of the roller circulation channel to the other one of the two opposite ends of the second section (UK1-2, UK2-2) of the roller circulation channel (UK1, UK2);
• wherein the roller deflection device (UV1, UV2) assigned to the respective one of the load-bearing roller passage channels (LK1, LK2) comprises at least a first row (RR1) of rollers (R1) and a second row (RR2) of rollers (R2), wherein the first row (RR1) of rollers (R1) and the second row (RR2) of rollers (R2) each comprise a plurality of rollers (R1, R2) arranged one after another and the first row (RR1) of rollers and the second row (RR2) of rollers are arranged next to each other in the roller circulation channel (UK1, UK2) of the roller deflection device (UV1, UV2) in such a way that when the guide carriage (10) is moved in the longitudinal direction of the profile guide rail (5), the rollers (R1) of the first row (RR1) of rollers and the rollers (R2) of the second row (RR2) of rollers circulate next to each other along the ring-shaped closed roller orbit through the roller circulation channel (UK1, UK2), in each case parallel to a predetermined first plane (E1, E2);
• wherein the full complement roller deflection device (UV1, UV2) assigned to the respective one of the load-bearing roller passage channels (LK1, LK2) comprises a separating web (TS), which is fixed relative to the main body (11) and extends in the roller circulation channel (UK1, UK2) parallel to the first plane (E1, E2) through the first section (UK1-1, UK2-1), the second section (UK1-2, UK2-2), the third section (UK1-3, UK2-3) and the fourth section (UK1-4, UK2-4) of the roller circulation channel (UK1, UK2) and is arranged between the first row (RR1) of rollers (R1) and the second row (RR2) of rollers (R2) in such a way that the separating web (TS) spatially separates the rollers (R1) of the first row (RR1) of rollers from the rollers (R2) of the second row (RR2) of rollers;
• wherein each roller (R1) of the first row (RR1) of rollers abuts a first lateral surface (F1) of the separating web (TS) with a front surface (SF1, SF2) of the respective roller (R1) so that each roller (R1) of the first row (RR1) of rollers rests against the first lateral surface (F1) of the separating web (TS) when the guide carriage (10) is moved in the longitudinal direction of the profile guide rail (5), and
• wherein each roller (R2) of the second row (RR2) of rollers with a front surface (SF1, SF2) of the respective roller abuts a second lateral surface (F2) of the separating web so that each roller of the second row (R2) of rollers is guided at the second lateral surface (F2) of the separating web when the guide carriage (10) moves in the longitudinal direction of the profile guide rail (5).
