A linear bearing arrangement consists of a guide rail (1) having a longitudinally running, tub-like depression (7) which carries two first ball tracks (10) in the region of its side surfaces (8) arranged inclined inwards, and a carriage (2) which has a bearing part (12), projecting therein and matched to the shape of the tub-like depression, on which there are arranged two second ball tracks, associated with the first ball tracks (15). In order to achieve a particularly simple and rigid structure for universal applicability, with the carriage requiring little space, the arrangement is designed such that the ball tracks (10, 15) on the guide rail (1) and on the bearing part (12) of the carriage (2) are designed in each case as profile grooves which are essentially arc-shaped in cross-section and partially surround the rows of balls on the side facing the opening of the tub-like depression (7), such that the carriage (2) is held via the bearing part (12) on the guide rail (1), such that it cannot be lost, and such that the bearing part (12) is rigidly connected to the carriage (2), or is designed as one piece therewith, the guide rail (1), designed as a carrier with a stable shape, having at least one mounting surface (5) on the side opposite the tub-like depression (7). <IMAGE> |
