Used in low-wind onshore and large offshore turbines from 2 to 10+ MW operating with load based individual pitch control (IPC) or high collective pitching activity

  • Provides extended pitch bearing lifespan thanks to unsurpassed raceway fatigue life
  • Higher capacity permits lower LCOE (Levelized Cost of Energy): smaller blade root diameters/hub sizes and/or longer blades possible
  • 3-ring design: T-shaped blade mounted ring, split hub mounted ring – solid as it should be for 25 years turbine life
  • Two rows of axial rollers offering load independent contact angles – no ring separation, reduced ring stresses
  • Safe operation requires a minimum pitching activity and sufficient bearing support


  • three-ring-design: T-shaped solid blade mounted ring, split hub mounted ring
  • two axial raceways, 90 deg roller contact angle
  • single row radial raceway, 0 deg roller contact angle
  • roller separation by spacers in axial raceways
