The guide tubes of the linear units are made
of chrome-plated steel or bright stainless steel
precision tubes. A continuous spindle with ball
bearings on each side is installed in the guide tube.
The spindle nut transmits the linear movements to
a linear unit connector via a drive key along the
guide groove.
Together with the guide tube, the guide element
bore forms a solid linear square guide mechanism
that can receive large torsional forces. Multiple
connector types are available for selection and can
be adjusted or clamped for low play using the split
bore. 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 linear unit connectors and the
accessories are not included with the linear units
and must be ordered separately.
Adjustable hand levers are intended for repeated,
tool-free clamping of the guide elements. Under
the designation HSK, these are available separately
for individual use and in other designs. Compared
with the tool-operated hex socket cap screw, the
clamping force achievable with an adjustable hand
lever is lower due to the shorter lever length.
