CONTI^®
Single Convolution Air Springs
As actuators, these units have the lowest compressed height and can execute strokes of up to 129 mm and exert forces of up to 40kN. As vibration isolators, they serve as laterally stable mountings with a favourable design height; they cover a natural frequency of between 2.3 and 3.8 Hz.

CONTI^®
Double Convolution Air Springs
As actuators, they perform strokes of up to 400 mm and exert forces of up to 900 kN. As isolators, they cover a natural frequency of between 1.7 and 2.6 Hz.

CONTI^®
Triple convolution
As actuators, they perform strokes upto 440 mm from a very low compressed height and exert force of up to 400 kN.

CONTI^®
Sleeve Type Air Springs
As actuators, these lightweight components execute strokes of up to 100 mm and can exert a constant force of up to 10 kN over the whole length of their stroke. As vibration isolators, they have a natural frequency of about 2 Hz. They can only be used if laterally guided.

CONTI^®
Rolling Lobe Air Springs
As actuators, these units perform strokes of up to 260 mm and can exert a constant force of up to 45 kN over the whole length of their stroke. As vibration isolators, they have a natural frequency of between 1.2 and1.6 Hz. They can only be used if laterally guided.
