Slewing Rings

Reliability and transparence

The slewing rings in a wind turbine, especially the pitch bearings, are subjected to enormous loads that lead not only to material fatigue, but also to wear. We observe problems in the field that create the need for greater clarity about the reliability of slewing rings. In the context of testing and certification, we provide this clarity as an independent third party between the manufacturer of wind turbines and the supplier of the component. Our methods encompass the application of numerical methods as well as validation with tests.
