A wind turbine includes a hub, at least one blade and at least one pitch bearing to connect the at least one blade to the hub. The at least one pitch bearing has at least an inner ring and an outer ring, and at least a rolling race. The wind turbine further includes at least a tensioning system configured to exert a radial compression force to at least a part of the outer ring of the at least one pitch bearing, thus increasing the resultant stiffness of the at least one pitch bearing.
