The guide tubes of the linear units are made of
chrome-plated steel or bright stainless steel precision
tubes. A spindle with ball bearings on both sides is
installed in the guide tube. This is comprised of one
part with left-hand thread and one with right-hand
thread. The spindle nuts positioned on the left and
right transmit the symmetrical and opposing linear
movements to two linear unit connectors via two drive
keys along the guide groove.
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 symmetrically moved 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.
