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.
