A hub for a rotor of a wind turbine is disclosed. The hub includes a hollow body rotatable around a rotation axis. The hollow body includes a blade flange and defines a blade flange area surrounded by the blade flange. The hollow body further includes a main shaft flange defining a first end, and a second end opposite the first end. The hub further includes a stiffening web extending within the blade flange area and defining a web plane. A side profile of the web plane extends from the first end to the second end is oriented at a cone angle to the rotation axis.
