ABSTRACT:
A sealing ring (5) which is intended to seal between two relative to each other axially movable parts (2, 7) of the rotor of a centrifugal separator, and which has edges bevelled such that it can be impressed in its sealing surface only when the recesses formed by the bevelling have been filled up by material from the sealing ring as a result of plastic deformation of the latter by compression between the rotor parts (2, 7).
