2. Function
Pressurized fluid is applied to a circular piston inside a
c
ylin

e
r
which pushes the rod. This action moves the piston g

t
ing
linear motion. This linear motion and force is transmitted to
t
h
e
application by the rod.
Where
specified, the sensor

5. Commissioning
Complete System
Slowly fill the complete hydraulic system with oil in order

prevent any uncontrolled movements. During the filling
operation, the system and/or cylinder must be bled of air

– Start a test run.
– If necessary adjust the cushion screw to achieve o

performance.
The
purpose of the cushion adjustment is
t
o
ensure that the cylinder achieves full stroke without s
