Wind turbine slewing bearings can also be called wind power bearings. They are a special kind of bearings. They are used in harsh environments, have high maintenance costs and require long life. Slewing bearings for wind turbines mainly include: yaw bearings, pitch bearings, spindle bearings, variable speed bearings, box bearings, generator bearings. 

The structural forms of slewing bearings for wind turbines mainly include four-point contact ball slewing bearings, crossed roller slewing bearings, cylindrical roller bearings, spherical roller bearings, and deep groove ball bearings. The yaw bearing is installed at the connection between the tower and the cockpit, and the pitch bearing is installed at the connection between the root of each blade and the hub.

Judging from the current installation and usage, the pitch slewing bearings mostly use double-row four-point contact ball slewing bearings, the yaw slewing bearings mostly use single-row four-point contact ball slewing bearings, and a small amount of cross-roller slewing bearings or other forms are used.
