Slewing Bearings for Wind Turbines

Wind Turbines Slewing ring bearings can be classified into three types: the yaw bearing, pitch or blade bearing, driving system bearing (spindle bearings and gearbox bearing).

The yaw bearings install into the joint between tower and cabin, the pitch bearing installed into the joint between the blades and hubs. Each wind turbine has a set of yaw bearing and three sets of pitch bearing.
