Many companies started to develop wind turbines are beginning to realize recently, high-performance hybrid ceramic ball bearings advantages, especially after using the hybrid ceramic ball bearings can be a wind turbine blade rotor shaft rotational speed of 30rpm raised to 2000rpm, to produce more electricity. Silicon nitride balls are ideal to improve bearing performance. Compared with the steel ball, the silicon nitride ball lighter, more rigid, more rigid, more smooth, corrosion-resistant, does not require much lubrication and having a lower coefficient of thermal expansion. These properties make the bearing can run faster, work at higher temperatures, and reduce lubrication maintenance. Silicon nitride ball extremely resistant to wear. And longer bearing life means that wind power plants to replace the bearings significantly extend the period of replacement cost is greatly reduced (due to the need to use lifting equipment when replacing the bearing, generally estimated replacement cost for each 70,000 yuan). This saving role especially in the high speed generator shaft system is more obvious.
