The round guides of the precision double tube
linear units are made of hard-chromeplated
steel or polished stainless steel solid shafts.
The aluminum CNC end pieces connect the solid
shafts and form a very precise linear guide together
with the guide elements. Two independent whirled
or rolled recirculating ball screws run through the
center of the assembly. The roller-guided double
guide elements are moved linearly along the
spindle threads by the integrated ball screw 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.
