Pneumatic cylinder / double-acting / rodless / high-speed

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).
In order to increase the load capacity, side shoes are mounted in addition to the
guide shoes normally present on the standard PU version. They run in grooves and
support the central element (cap), which has a carriage-piston rocking coupling.
This means the carriage only transmits axial loads; it does not support loads and
moments in other directions. Shoe clearance can be adjusted by means of lateral
threaded screws to reduce wear. The shoes can be replaced without having to
remove the cylinder. This family of cylinders has the same features as described for
the basic version, such as built-in adjustable pneumatic cushioning and sensor and
accessory slots. A version with adjustable limit switches and hydraulic decelerators is
available. They can be purchased and added at any time, even to basic cylinders.
