Pitch Bearing Seals for the Largest Wind Turbines in the World
Challenge
Large-diameter seals in wind turbines became dislodged from their housings, causing loss of bearing grease, water ingress and significant damage to the pitch bearings.
Solution
System Seals redesigned the bearing groove dimensions and created a multi-faceted, high-performance seal.
Result
The new seal performed flawlessly in initial lab tests and then for more than a year in the field. System Seals now produces all new pitch-bearing seals for one of the largest wind turbine manufacturers in the world.
