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: 20 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.

direct use of bump stops or external stops. Do not combine an
angular motion and a misalignment. Avoid using below
