Abstract: A sealing arrangement (34) for a main bearing (21) of a wind turbine (1). The sealing arrangement comprises a first seal (35) configured to be disposed on one axial side of the main bearing (21) and including a first O-ring (80), and a second seal (36), configured to be disposed on an axial side of the main bearing opposite the first seal. The second seal comprises a second O-ring (41) retained within a sealing holder assembly (40) that comprises multiple annular parts, including a ring- shaped inner fixture plate (43), configured to be disposed adjacent the main bearing, a ring-shaped basis fixture plate (44) and, on an axial side of the basis fixture plate opposite the inner fixture plate, a ring-shaped outer fixture plate (45). Preferably, at least one of the fixture plates (43, 44, 45) is formed of 4 to 8 arcuate plate parts.
