Double-tube linear axis PD3D series

manualaluminumprecision

The guide tubes of the precision double tube linear units PD3D are made of chrome-plated steel or polished stainless steel precision tubes. The end pieces of aluminum connect the tubes and form a precise linear guide together with the guide elements. The centered independent spindles have trapezoidal or fine thread and ball bearings on both sides. The slide-guided double guide elements are moved linearly along the spindle threads by the integrated spindle nuts – independently of the opposite side. Double tube linear units have high torsional stiffness and can handle high weights and torques. The double guide element distributes the load among four guide points, allowing for even higher loads. Accessory parts are listed in the tables and are already taken into account when selecting the linear units. This ensures, for example, that the lengths of the journals z1 and z2 are correct for attachment of the accessories. The accessories are not included with the linear units. RoHS-compliant product
