The 20mm Series Profile Guide Rail system is a high capacity and high rigidity bearing system designed for the toughest applications, like large cartesian systems and range extenders for larger cobots. These rails come in six lengths: 360mm, 585mm, 855mm, 1530mm, 2295mm, and 3330mm. If a longer guiding system is needed the rails can be butt-joined. See the technical document page for more details.
