1. A rotor hub for a wind turbine, comprising:
- a hollow shell defining an interior; and
an annular member integral part of or connectable to a bearing,wherein the rotor hub is adapted to be connected to a plurality of rotor blades,wherein the bearing is adapted to rotatably mount the rotor hub to a stationary main shaft of the wind turbine,wherein the annular member protrudes inwards into the interior of the rotor hub; and
wherein the annular member extends axially inwards into the interior from a side of the hollow shell configured to face, when the wind turbine is assembled, the stationary main shaft of the wind turbine.

Abstract
A wind turbine is provided. The wind turbine includes a stationary main shaft arranged within a nacelle of the wind turbine, a rotor hub including a hollow shell defining an interior and a plurality of rotor blades extending radially outwards from the rotor hub, wherein the rotor hub is rotatably mounted to the stationary main shaft via at least one bearing, wherein the at least one bearing is arranged within the interior of the rotor hub and connected to a section of the main shaft protruding into the interior of the rotor hub.
