Abstract
A root bushing for a blade root of a wind turbine rotor blade, including a cylindrical bushing body and a flat contact body is provided. The contact body is provided on a face of the bushing body. This has the advantage that due to the provision of the contact body, the contact area between the root bushing and the pitch bearing is increased. In another embodiment, the root bushing includes a central bore which protrudes through the bushing body and the contact body. In another embodiment, an outer wall of the bushing body is provided with a connection structure for connecting the root bushing to a composite material of the wind turbine rotor blade.
