Abstract

A pneumatic cylinder with damping in the end position, also comprising a housing in which at least one slide rod element is mounted with at least one sealing element, in such a way that said slide rod element is linearly displaceable. At least one damper sleeve or its bearing arrangement is associated with the slide rod element, said bearing arrangement engaging with front-end bearing elements in the end positions. According to the invention, the damper sleeve or its bearing arrangement has at least one indentation for damping the end position and for ventilation.
