WinWinD, a Finnish manufacturer of wind turbines, has made an agreement with SKF, one of the world's leading bearing manufacturers, concerning main bearings to be supplied for WinWinD's three-megawatt wind turbines.
A wind turbine main bearing receives the load from the wind to the main gear unit, which increases the rotor speed to a convenient level for the generator. The main bearing, among the main gear unit, is one of the most important mechanical components in the wind turbine. It is expected to be highly reliable during the calculated turbine life time.
