Abstract: The invention relates to a method of prolonging pitch bearing lifetime for a wind turbine as well as the pitch bearing itself. The method comprises the steps of: —stopping the rotor (4) from rotating; —removing a plurality of first fastening means used for mounting the blade (5) to the outer bearing ring (24); —mounting a strengthening arc structure (10) on said outer bearing ring (24), opposite the blade (5); —installing a plurality of second fastening means, thereby connecting said blade (5) and said strengthening arc structure (10) to said outer bearing ring (24).
