The invention relates to a bearing arrangement (70) for a wind turbine (10) comprising a bearing housing (80) and a drive shaft (90), whereby the drive shaft (90) is arranged within the bearing housing (80) in an axial direction along a longitudinal axis (A) of the bearing housing (80), the bearing arrangement (70) further comprising a downwind bearing (100) and an upwind bearing (200) as radial fluid bearings, whereby the downwind bearing (100) and the upwind bearing (200) are arranged between the bearing housing (80) and the drive shaft (90). The downwind bearing (100) and/or the upwind bearing (200) comprises a lubricant flooded chamber (101, 201), in which multiple radial bearing pads (105, 205) are arranged about the drive shaft (90), whereby the lubricant flooded chamber (101, 201) is sealed against the drive shaft (90), an internal space (82) of the bearing housing (80) and an outside of the bearing housing (80).
