Abstract

The invention relates to a piston for a piston-cylinder arrangement, particularly a shock absorber piston, which includes a piston body, that has a circumferential surface. A sealing collar has an outer circumferential surface, an inner circumferential surface, a first peripheral surface, and a first sealing lip, and extends around the circumferential surface of the piston body and covers at least part of the circumferential surface in the axial direction. The first peripheral surface connects the two circumferential surfaces to each other at a first end of the sealing collar. The first sealing lip is delimited by the first peripheral surface and the outer circumferential surface, and the first sealing lip is configured evenly in the circumferential direction.
