The "endless" linear unit Typical fields of application The combined technology
for guiding, transporting and posi-
tioning over long strokes, offers:
Long travel distances, up to
50 m
High speeds in practical appli-
cations, up to 5 m/s
High levels of load capacity,
horizontally up to 1000 kg /
vertically up to 300 kg
Up to 64 Nm permitted drive
torque
Repeatability, up to ±0.05 mm
Several carriages possible on
one linear unit
Two profile sizes: HLEZ100
and HLEZ150
Simple, rapid installation and
start-up
as part of advanced, cost-effec-
tive construction of machines and
handling systems:
Materials handling
e.g. pal-
letization, feeding, removal
Textile machinery building
e.g. cross-cutting, slitting and
stacking, quilting, seam stitch-
ing
Process engineering
e.g.
painting, coating, bonding
Storage technology
e.g.
commissioning, inventory
Construction
technology:
e.g. peeling, laying reinforce-
ment of concrete
Clean room technology
e.g.
wafer transport, wafer coating
Machine tool building
e.g.
workpiece loading, tool chan-
ging
Testing technology
e.g.
guiding ultrasonic sensors
of the linear actuator and rack of-
fers the following advantages:
High dynamic response, even
over long travel distances, due
to:
the short timing belt, regard-
less of travel length
the lightweight carriage
the backlash-free drive
High positional accuracy, re-
gardless of stroke length
Option of several carriages per
linear unit, making overlapping
strokes along a single axis pos-
sible
Easy servicing at long intervals
Grooves running in the profiles
on all sides to enable mounting
of the HLEZ to a supporting
structure, fitting attachments or
as cable ducts
Grooves in the load attachment
plate for flexible installation
