The end disk (16) has a sealing arrangement (22) for forming a seal between the clean side (50) and the crude side (52). In addition, the sealing arrangement (22) has a sealing region (23) that forms a radial seal and a separate holding region (20) arranged concentrically with the sealing region (23) and acts as a radial floating bearing. The invention also relates to a filter system (100) for replaceable installation of such a filter element (10).
