single row ball slewing ring

Fan rotor slewing support. The function of the rotary bearing is to rotate the blade installed on the hub. The outer ring is connected with the hub by bolts, and the inner ring is connected with the blade. When the wind speed is too high or too low, the Angle of attack of air flow to the blades is changed by adjusting the pitch of the blades

Bearing selection for low-speed appliions | Kaydon Bearings white papers - Thin section bearings, slewing ring bearings, bearing …

Wind turbines are a good example: since the blade pitch bearings don''t rotate completely, the areas of the bearing that get the most use will show more wear and even false brinelling. Such appliions need lubricants with high film strength or extreme pressure additives, and sometimes self-lubriing separators for the rolling elements.
