A linear guide unit, in particular a gantry axis, that has an oblong guide support (), is provided with two essentially parallel guide rails () extending in the guide direction (F), but rotated in relation to each other around a rotation axis (V) parallel to the guide direction (F), each of which guide rails () has at least one sliding carriage () guided on it so that it can slide in the guide direction (F), the sliding carriages () being connected to a sliding carriage assembly () capable of moving as a unit in the guide direction (F). According to the present invention, the two guide rails () rest essentially without moving play against at least two counterpart support surfaces (GF, GFL, GFR, GF, GFL, GFR) of the guide support () extending essentially in the guide direction (F), two of the counterpart support surfaces (GF, GFL, GFR, GF, GFL, GFR) enclosing a predetermined angle, preferably of at most 90&#xb0;, between them.

Linear guide unit, in particular gantry axis

In a linear guide unit that has an elongated guide housing which limits a guide hollow space with a longitudinal opening, a wagon arrangement which is displaceably guided in the guide hollow space on guide rails, a connection part for connecting the wagon arrangement to an object to be guided, a cover element arranged between movement tracks of the connection part and covering the longitudinal opening, in accordance with the present invention forwardly of and/or rearwardly of the wagon arrangement, at least one support unit is arranged displaceably in direction of the longitudinal axis for supporting the cover element relative to the guide housing; also additionally or alternatively the support unit can support the cover element relative to the wagon arrangement.
