Abstract
A vacuum pump comprises stator elements in a pump housing. The stator elements cooperate with rotor elements. The rotor elements are held by a rotor shaft, wherein the rotor shaft is mounted in the pump housing via bearing elements. The bearing element is surrounded by a supporting element, wherein the supporting element comprises an inner portion, an outer portion and a plurality of spring arms connecting the inner portion (28) to the outer portion. Each spring arm comprises at least one hollow space.
