Pitch Bearing

UWE double row ball slewing bearing is mainly made up of inside and outside rings. The diameters of up-row and down-row balls are the same. It is suitable for high precision mounting and capable to bear axial force, resultant torque and considerable large radial force.
Double row ball slewing rings are widely application in wind turbine bearing (blade bearing/pitch bearing) and types of marine cranes.
Three types of this kind of double row ball slewing bearings:
A. Without gear bearing (non tooth)
B. External gear bearing (external tooth)
C. Internal gear bearing (internal tooth)

External gear blade bearing  External gear blade bearing  Internal gear blade bearing
