Extending wind turbine life with pitch bearing upgrades - …

3/2/2020· What makes pitch bearings unique. A pitch bearing upgrade can increase turbine life and efficiency while reducing costly downtime, all at a fraction of the cost of investing in a new turbine. Slewing ring bearings connect the rotor hub (spinner) with the blade so it can be adjusted to the optimal angle for wind conditions.
