A yaw or pitch bearing for a wind turbine includes a slewing ring bearing assembly having an outer race and an inner race, both having an inner surface and an outer surface. The inner surface of the outer race and the outer surface of the inner race have a plurality of threads that engage and define a threaded bearing surface.
