Abstract
A rotationally symmetrical bellows has a first end ring and a second end ring with a smaller diameter, and multiple folds, which in a relaxed position each have two flanks running in opposite directions with respect to one another while forming a bend. The flanks extend approximately parallel to an axis of rotation of the bellows. The rotationally symmetrical bellows is designed such that in a relaxed position of the bellows, the second end ring is arranged at an axial distance to the first end ring.
