Abstract
A linear guide device comprises a guide rail (10) with a longitudinal axis (12) and at least one guideway (16), as well as a runner carriage (14) guided at the guideway (16), in the direction of the longitudinal axis. The guideway (16) is covered before and after the runner carriage (14) in the direction of the longitudinal axis (12) substantially over its entire length by a cover strip (56) which in one embodiment lies against two cover strip contact zones (58), disposed on both sides of the guideway (16), of the guide rail (10). The guideway (16) and the cover strip contact zones (58) are in particular formed at a rail body of the guide rail (10) which is of a uniform base material. The cover strip (56) protects the guideway (10) against contaminants which may cause damage to the guideway (16) and impair the smooth running and guide precision of the runner assembly (14) on the guide rail (10).
