pneumatic cylinder / rodless / double-acting / long-stroke

Series PU rodless cylinders have an internal strip for longitudinal tightness made of
polyurethane (PU) with a harmonic steel wire core. This solution gives excellent air
tightness values. It is particularly suitable for high-speed and highly cyclical
applications, even with long strokes.
The external strip, which merely provides protection against of foreign bodies entry,
is made of harmonic steel. The anodised aluminium cylinder liner has a T-slot on
either side for housing the retracting sensors.
Cylinder control solenoid valves can also be housed in these slots and secured by
means of plates and screws (see General Catalogue page 1-46).
A hardened and tempered steel guide is firmly connected to the side of the liner to
increase overall performance. This gives the following features:
•
very high load capacity with forces acting in any direction and no transmission to
the cylinder carriage;
•
ball recirculation shoes constructed using special technology that makes them very
silent during movement of the guide and gives very long maintenance time
intervals; lubrication must be performed every 2000 km or once a year, using
type 2 grease, preferably with a lithium soap base;
•
extra-sturdy carriage support with numerous load fixing holes and centring pin
holes;
•
stroke range 100-2470 mm with 1mm intervals.
One version has shock absorbers + adjustable limit switches.
These can also be added at a later stage by purchasing the relevant kit.
