Method for manufacturing slewing ring bearing components having an integral stiffener

A method for manufacturing a slewing ring bearing for a wind turbine, the method comprising:

• forming an outer race of the slewing ring bearing of a first base material;
• providing a mass of a second base material, the first base material the same as or different from the second base material;
• forming the mass, via ring rolling, into an inner race of a slewing ring bearing, the inner race defining a circumferential surface comprising a stiffening region integral thereto;
• arranging the inner race within the outer race;
• and
• providing a plurality of roller elements between the outer and inner races.
