A compressed air landing strut 2 is disclosed with a pneumatic shock absorber which is set onto a spring support 14. The spring support 14 has an offset 22 and the end region 24 of the roll-off piston 12 is flared radially outward, so that it surrounds the offset 22. An O-ring 24 is radially compres

A compressed air landing strut 2 is disclosed with a pneumatic shock absorber which is set onto a spring support 14. The spring support 14 has an offset 22 and the end region 24 of the roll-off piston 12 is flared radially outward, so that it surrounds the offset 22. An O-ring 24 is radially compressed between the outer wall 40 of the spring support 14 and the inner wall 42 of the roll-off piston 12 and seals the spring space 4 of the pneumatic shock absorber air-tight against the environment. A method for the manufacture of said pneumatic shock absorber is also disclosed.

1. A compressed air landing strut comprising:a pneumatic shock absorber with a rolling bellows which encloses a spring space, a roll-off piston along which the rolling bellows can roll, a spring support that is plunged into the roll-off piston, with an offset in which the roll-off piston is braced, a ring-shaped gasket which is located between the spring support and the roll-off piston, and seals the spring space against the environment, wherein on the offset of the spring support there is the ring-shaped gasket in form of an O-ring whose cross sectional surface diameter is sized so that it covers at least the width of the offset, and that the end region of the roll-off piston facing the spring support is flared radially outward, and the spring support is plunged into the roll-off piston in such a manner that and the roll-off piston is braced in the axial direction against the offset, whereby the O-ring is located between the offset and the inner wall of the roll-off piston in such a manner, that the O-ring is compressed radially between the outer wall of the spring support and the inner wall of the end region of the roll-off piston.
