Abstract
A stator-rotor arrangement for a vacuum pump, in particular for a turbomolecular pump, includes a plurality of stator disks () that cooperate with a rotor element (). The stator disks () are disposed between rotor disks (). The stator disks () are held by way of stator rings (). At least two of the stator rings () include protrusions () that are connected together by way of holding elements (). This makes pre-installation of the rotor-stator arrangement () or placement of the rotor-stator arrangement () in a housing () possible. The protrusions () are disposed in the area of corners () of the housing ().
