Key features
Key features
Bellows actuators function both as
driving and pneumatic spring com­
ponents. Bellows actuators function
as a driving component by providing
supply and exhaust functions. As the
stroke increases, the force generated
is reduced in relation to the

Combined installation
de
Lateral offset
The max. lateral offset must not be
exceeded.
When using two or more bellows
actuators, the necessary mounting
plates must be inserted between the
cylinders to prevent a lateral break
out.
Tilted installation
smax
Minimum height
The max. tilt angle á must not be
exceeded to ensure that the bellows
walls cannot touch.
Maximum height
The bellows actuator must not fall
below a min. height, otherwise it will
be damaged.

bellows. There are no sealing compon­
ents and no moving mechanical parts.
Bellows actuators are single-acting
drives that do not require spring
returns, as the reset is achieved by the
application of external force.
hmax

contractional force of the bellows.
When bellows actuators are supplied
with permanent pressure, they act as
a cushioning component. The simple
design consists of two metal port
plates with an attached rubber
hmin
Suitable for use in harsh, dusty
ambient conditions
Can be used under water
Sturdy design
Large forces range from 1 … 50 KN
Low installation height
No stick-slip effect
Maintenance-free
The bellows actuator must not exceed
a max. height, otherwise it will be
damaged.

Corrosion resistance class CRC 0 to Festo standard FN 940070
No corrosion stress. Applies to small, optically irrelevant standard parts such as threaded pins, circlips and clamping sleeves which are usually only available in a phosphated or burnished version (and possibly oiled)
as well as to ball bearings (for components < CRC 3) and plain bearings.
Corrosion resistance class CRC 2 to Festo standard FN 940070
Moderate corrosion stress. Indoor applications in which condensation may occur. External visible parts with primarily decorative requirements for the surface and which are in direct contact with the ambient atmo­
sphere typical for industrial applications.

Note
Bellows actuators may only be
driven against a workpiece, or they
must be equipped with stroke
limiting stops at the stroke ends,
because the bellows walls would
otherwise be overloaded or internal
damage could occur.
2014/06 – Subject to change
A resetting force is required to
press the bellows actuator together
to its minimum height. As a rule,
this is achieved through the weight
force
The entire bearing surfaces of the
upper and lower plates must be
utilised to absorb forces
Bellows actuators must be
exhausted before disassembly
è Internet: www.festo.com/catalogue/...
The walls of bellows actuators must
not come into contact with other
parts during operation
