Yaw bearing is mounted between the connection of tower and cabin. Pitch bearing is mounted between the connection of blade root and wheel hub. Each wind turbine generator comprises of one yaw bearing and three pitch bearings, the material of the rolled rings is 42CrMo with quenching and tempering. Raceway surface intermediate frequency induction hardened.
Due to complexity of the stress situation, the bearing must bear impact and carry high load. 20 years is a required lifetime for the wind turbine generator, it is also required by yaw bearing and pitch bearings as the mounting cost is too high.
LYJW is a leader in the manufacturers of large size slewing bearings, based on Luoyang in China which designs and manufactures a large variety of ball and roller slewing ring bearings with diameters range from200mm to 6500mm in many applications that require long operating life under demanding conditions. The slewing bearings are widely used as components in wind energy turbines, harbor cranes, ship deck cranes, truck cranes, construction cranes, bulk materials handlings, port machinery, ladle turret or Ferris wheels etc.
