Abstract
A shock absorber with a pneumatic spring, comprising an outer suspension tube and an inner suspension tube of a suspension unit, whereby elastic roller bellows are connected to the outer and inner suspension tubes, forming a spring chamber. The roller bellows are crimped on one end to the inner suspension tube. When the shock absorber with a pneumatic spring is fully assembled, a safety device is located on the pneumatic spring which centers the outer suspension tube in relation to the inner suspension tube, so that contact between the crimped part and the adjacent roller bellows is prevented, thereby preventing damage to the roller bellows.
