Double-tube linear axis VD2E series

manualaluminumprecision

The guide tubes of the double tube linear units VD2E are made of chrome-plated steel or polished stainless steel precision tubes. The aluminum end pieces connect the tubes and form a solid linear guide together with the two guide elements. A continuous spindle with ball bearings on both sides is installed in the center. This is comprised of one spindle part with left-hand thread and one with right-hand thread. Together with the single guide elements, the affixed spindle nuts move linearly in opposing directions 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. Possible accessories are already taken into account in the selection of the linear units according to the options given in the tables. This ensures, for example, that the journal lengths z1 and z2 are appropriate for attachment of the accessories. The accessories are not included with the linear units.
