General information
Weight of the bellows 1.2 kg
Air springs must not be pressurised unless they are restricted by
an outside frame or by a suitable load. Respect the minimum and
maximum height specifications (the high position of your
application must be lower than the air bellows maximum height
and the low position of your application must be higher than the
direct use of bump stops or external stops. Do not combine an
angular motion and a misalignment. Avoid using below

Bellows are entirely dismountable. Bellows are single acting air actuators and can be used as actuator or isolator. Indicative value of force to
reach the minimum height: 14 daN. When tracking air springs, special care must be taken to ensure the air springs are guided and fixed.
For other kinds of rubber compounds, contact our technical sales department.
