Beschreibung
Zusammenfassung:	The invention is directed to a bearing unit (1) for a rotor unit (2) of a wind turbine (3), comprising a first bearing ring (4), a second bearing ring (6), a plurality of rolling elements (8) and a sealing member (11) comprising a sealing member base portion (12), a first sealing member tip portion (13) and a second sealing member tip portion (14), wherein the first sealing member tip portion (13) abuts a first wall (15) of the first bearing ring (4) and the second sealing member tip portion (14) abuts a second wall (16) of the bearing unit (1), wherein the sealing member (11) is configured and arranged such that a first contact pressure between the first sealing member tip portion (13) and the first wall (15) is transmitted through the sealing member (11) to the second sealing member tip portion (14) to increase a second contact pressure between the second sealing member tip portion (14) and the second wall (16). The invention is further directed to a wind turbine (3).
