Filter element and filter system having a filter element

A filter element for a filter system for filtering a fluid, the filter element comprising:

• a longitudinal axis;
• a filter bellows arranged about the longitudinal axis and enclosing an interior of the filter element;
• an end disk comprising an opening to the interior of the filter element;
• wherein an axial outer surface of the end disk has a radial outer rim forming an axially extending circumferential first radial outer surface,
• wherein the first radial outer surface forms a radial outwards step to a to form a radial protrusion as an axially extending circumferential second radial outer surface,
• wherein the radial protrusion is spaced radially outwardly away from the first radial outer surface of the end disk,
• wherein the radial protrusion forms a circumferentially extending radial seal configured to seal against a sealing surface of a housing when in an installed state,
• wherein the radial protrusion extending extends past the filter bellows in a radially outward direction in relation to the longitudinal axis.

A filter system for filtering a fluid, the filter system comprising:

• a housing comprising
• a cover and
• a housing part closable by the cover;
• a filter element configured to be exchangeably arranged in the housing,
• wherein the filter element comprises
• a longitudinal axis and
• a filter bellows arranged about the longitudinal axis and enclosing an interior of the filter element,
• wherein the filter element comprises
• an end disk comprising an opening to the interior of the filter element,
• wherein the end disk comprises a bead arranged about an outer circumference of the opening to the interior and surrounding in one-piece at least 60% of the outer circumference of to the opening to the interior,
• wherein the bead projects outwardly away from the end disk in a direction of the longitudinal axis;
• wherein the bead, in a mounted state of the filter element in the housing, engages a complementary receptacle arranged at an inner side of the cover.
