The invention relates to a linear guide consisting of a rail (1) with severa l tracks (2) and a cradle (3), which comprises at least one sliding element (4 ) that lies opposite the tracks (2), said element having an inclined surface ( 5) on the side facing away from the rail (1). Between the sliding element (4) a nd the cradle (3), the guide is provided with a displaceable actuating element (6), one surface (7) of which lies on the inclined surface (5) of the slidin g element (4) in such a way that it can be displaced. To automatically adjust the bearing play, the actuating element (6) is pre-tensioned against the inclined surfaced (5) of the sliding element (4) in such a way that a force component is produced on the sliding element (4) perpendicular to the tracks (2) that lie opposite said sliding element (4). In addition, the adjacent surfaces (7, 5) of the actuating element (6) and the sliding element (4) hav e a corresponding stepped configuration, so that the steps of the relevant surface (7) of the actuating element (6), as a result of the pre-tensioning of the latter, can slide over the steps of the inclined surface (5) of the sliding element (4) that is displaced in the direction of the tracks of the rail (1), with a corresponding amount of play. |
