Across North America, many pump generating stations exist, with several of them, being plagued by thrust bearing failure. All pump storage stations are large as compared to most other hydroelectric stations, meaning that failures are expensive in nature. The main issue with bearings for a pump storage generator/turbine set is that the bearings must support large loads when the unit is turning in either direction.
