A wind turbine slewing bearing is a large rotating component that connects major parts of the turbine. Two types are critical: pitch bearings sit between the hub and each blade, adjusting blade angles to capture the best wind energy. Yaw bearings sit between the tower and the nacelle, […]

A slewing bearing—also known as a slewing ring or turntable bearing—is a large-diameter rolling-element bearing designed to support heavy loads while enabling rotational movement between two structures. Unlike standard bearings that handle primarily radial or axial loads, slewing bearings are engineered to simultaneously manage axial loads (vertical forces), radial loads […]

A three-row roller slewing bearing is a large-diameter rolling-element bearing that uses three independent rows of cylindrical rollers to support loads. Unlike single-row ball bearings or crossed roller designs, the three-row roller configuration dedicates separate roller rows to different load directions. The upper and lower rows of rollers […]

A slewing bearing operates at the intersection of heavy loads, slow rotation, and harsh environments. Unlike high-speed bearings that rely on hydrodynamic lubrication films, slewing bearings often work under oscillating motion and high static loads. Their performance and service life depend not on speed, but on […]
