Ball bearings can be reliable. There is an old power generating station in a ghost town named Sandon located in the Selkirk Mountains of BC. 17000 feet of wooden pipe brings water down the mountain feeding a turbine that has been running for over 100 years. It used to provide power for the town and a old nickel mine but now is tied to the grid. The shaft joining the turbine wheel to the generator is supported by the original wet ball bearings that have yet to require replacement. I suppose dirty gear oil might not provide the same level of lubrication.....
