The guide tubes of the precision double tube
linear units 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.
