Abstract
Method for increasing the fatigue strength of a mechanical part of a wind turbine and/or for reducing the tendency to form what are called “white etching cracks” or “brittle flakes” in such a bearing, which includes making one or several of the bearing rings and/or roller elements concerned of the bearing at least partly of a hardened steel having a carbon content between 0.4 and 0.8 percent by weight.
