Self-cleaning filter assembly and roller bearing assembly, and methods of self-cleaning

The invention relates to a self-cleaning filter assembly having a rotatable filter element (3, 26, 27, 34) for applying an axial Anflussstrom (9), wherein the self-cleaning filter assembly is provided for a first part of the Anflussstroms (9) (a filtered current to generate 10) and a second part of the Anflussstroms (9) by means of a radial free space (5, derive 42), wherein the second part of Anflussstroms (9) from the surface (39, 46, 47) of the rotating filter element (3, 26, 27, 34) captured particles (6) is laden, and a purge stream (41) is formed. It is thus achieved that can be the action of a fine filter and a rotary separator ideally combined, so that a space (43) advantageously of a rolling bearing area (44) and the particles present therein (6), can be protected.
