Bellows and diaphragm cylinder

Bellows cylinders: Drive and pneumatic spring elements for harsh, dusty environments or for use under water

Rolling bellows with large stroke range in relation to the height

Fluidic muscle as a tensile actuator modelled on a biological muscle, with almost linear force-stroke characteristics
