<p>Two parallel bearing rails (15, 16) are arranged one above the other on one support (1) and a running rail (17) running between and parallel to the bearing rails (15, 16) is arranged on the other support (2). The bearing rails and the running rail extend over the whole length of the respective bearing. Each bearing rail (15, 16) has longitudinal grooves (18, 19, 20, 21) on its upper and lower longitudinal face which constitute a continuous track for the roller bodies (22) which are conveyed in an endless series by strap-like holding devices hanging together. Counter-tracks (23, 24) are provided on the running rail (17). The roller body holding devices have spaces (32) on both sides running parallel to the track. The roller body holding devices are fed laterally into the longitudinal grooves (18, 19, 20, 21) at these spaces (32). This longitudinal bearing makes possible precise longitudinal guiding of elongated bearings, is very compact, easy and inexpensive to manufacture, and can be adapted to any length of support.</p> |
