Beschreibung
Zusammenfassung:	The invention concerns a backing device (40) adapted to equip an axlebox (10) comprising a bearing unit (30) and supporting an axle (6). The backing device (40) comprises an inner ring (250) having an inner surface (51) and at least one outer surface (252), at least one outer ring having an inner surface (262) facing the outer surface (252) of the inner ring (250); and tightening means (180) inserted inside the inner ring (250) and/or the outer ring (260). The tightening means (280) comprise at least one cavity (281) formed inside the inner ring (250) and a valve (282) inserted inside the inner ring (250) in fluid communication with the cavity (281); and wherein the tightening means (280), when actuated by filling the cavity or cavities (281) with a fluid (F1), press the outer surface (252) of the inner ring (250) and the inner surface (262) of the outer ring (260) against each other and narrow the inner surface (51) of the inner ring (250) by elastic deformation thereof.
