The guide tubes of the double tube linear units VDSE are made of chrome-plated steel tubes. The aluminum end pieces connect the tubes and form a solid linear guide together with the guide element. A continuous spindle with ball bearings on each side is installed in the center. Together with the single guide element, the affixed spindle nut moves linearly along the spindle thread.
Double tube linear units have high torsional stiffness and can handle high weights and torques. Depending on the design, the part to be moved is fastened to the guide element or the guide element itself is installed at the place of use such that the entire linear unit moves together.
