They are used, for example, in handling or automation applications and in jigmaking, for straight-line traversal distance when large extension and a low construction height of the rail are required. The H-shape of the rails profile gives the configuration a high degree of sturdiness. The rails and runner are equal in length. Both rails can be extended so that an extension is reached which is longer than the base length l 1 . Removing the support screws from the rails allows a stroke of the run- ners on both sides. The position of the rail is defined only at the two end positions. Depending on the requirements, three types are available with different mounting holes. External elements should limit the maximum sliding di- stance; the supports of the rail have been designed to guard against the inadvertent extraction of the runner from the rail. see also... • Structure Linear Slides → Page 1906 • Linear Guide Rail Systems → Page 1918 ff. • Load Rating of Telescopic Linear Slides → Page 1914 ff.
