GN 2408 telescopic linear slides with H-shaped rail consist of two interconnected linear motion bearings. 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 l1. Removing the support screws from the rails allows a stroke of the runners on both sides.
External elements should limit the maximum sliding distance; the supports of the rail have been designed to guard against the inadvertent extraction of the runner from the rail.
Available upon request:
• other lengths (based on the standard lengths grid dimension of 80 mm)
• special lengths (between d2 bores, start and end distances)
