Abstract: A rotor (1) for a wind turbine is disclosed. The rotor (1) comprises a hub (11) and at least one wind turbine blade (10), each wind turbine blade (10) being mounted on the hub (11) via a bearing unit (2). Each bearing unit (2) comprises a C-shaped bearing element (3) forming an inner ring and a T-shaped bearing element (4) forming an outer ring. The C-shaped bearing element (3) comprises a first bearing element part (12) and a second bearing element part (13). An interface (14) between the first bearing element part (12) and the second bearing element part (13) is positioned in such a manner that a third raceway pair (8) is formed between a protruding portion (5) of the T-shaped bearing element (4) and the first bearing element part (12) of the C-shaped bearing element (3) and the hub (11) or the wind turbine blade (10) is attached to the second bearing element part (13) of the C-shaped bearing element (3).
