Slewing Ring Bearing Balls for Wind Energy

Wind turbine bearings are important components of wind power generator.According to the installation location, wind turbine bearings could be divided into main shaft bearings, yaw bearings and pitch bearing etc. The life of wind turbine bearings are required to last more than 20 years as the working environment is tough and maintenance cost is very high. Therefore, wind turbine bearings have strict quality requirements on steel balls.Yusion carries out standard management systems strictly according with proprietary standard regulated by international technology criterion of steel to select our raw material.And by advanced facility, top-ranking testing intruments and stringent control procedures to guarantee our wind energy steel balls with superior quality and long life.
