The guide tubes of the linear units are made
of chrome-plated steel or bright stainless steel
precision tubes. Two independent spindles with ball
bearings on each side are installed in the guide tube.
The thread direction of the spindles can be chosen
as desired for each side. The spindle nuts positioned
on each spindle transmit the linear movements to a
linear unit connector via a drive key along the guide
groove, independently of the opposite side.
Together with the guide tube, the guide element
bores form solid linear square guide mechanisms
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. The parts to be moved are fastened to the
guide element, such as for format adjustments, in
which one side guide is moved independently from
the opposite side to various widths.
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.
