Double-acting cylinders
CDRA
CD Series
HYDRAULIC CYLINDERS
Working pressure: 700 kg/cm
2
/10.000 psi.
All pistons have a salt bath nitriding treatment
or a hard chrome plating, depending on the
model, to resist corrosion and for longer life.
With built-in bronze guide for easier sliding
of piston.
Fitted with a relief safety valve, ref. A-5538
on the piston retract side, to prevent accidental
overpressure.
These cylinders are fitted with a removable
grooved saddle, pressure mounted or screwed
in the piston head. Are also equipped with
a high flow female quick coupler with dust
cap, ref. A-5507-H.
Carry handles on models weighing from
20 kg/44 lbs to 40 kg/88 lbs. Heavier models
are fitted with eye hooks for transport.
With mounting holes and threaded areas
protected against blows for easy coupling or
special tooling applications.
The hydraulic force being applied in both
directions, these cylinders are very solid and
used where a precision operation is required
to move or position loads accurately on the
assembly place. Widely demanded in public
works and big structure manufacture.
