Wear in wind turbine pitch bearings—A comparative design

Nov 12, 2021· The results for angular contact ball bearings of the size 7208 (60-mm pitch diameter) 10 and first results of a four-point contact ball bearing of a 7.5-MW wind turbine (4690-mm pitch diameter) 57 show similar wear marks to the ones presented in this paper. The comparability of the results is not statistically secured due to the small sample size.
