6205 Bearings, 8 ball vs. 9 ball

[Patrick Star]

I found some bearings in the garage the other day, they are 9 ball 6205 bearings and the Yamaha pump has 8 ball count 6205, what's your thoughts on the wear rate? Would they be a suitable bearing? I know the higher ball counts are good for static loads and lower RPMs.

won't matter much as rotation speeds are much below rated.
9 will actually offer better longevity but not something you'll be able to prove in this application.
