One of us has missed the point. Since there is an eightfold increase in single row failures there has to be a heavily weighted variable, one might even hazard to say exponentially weighted in favor of the dual row bearing. Assuming the Porsche designers had not been pithed just before designing the single row ( A
distinct possibility), the bearing loads and speeds should pan out. As speed and loads should be accommodated, that would seem to leave lubrication. So what have I missed?
And Jake - I had no idea the 6204 was used in GM alternators! It's also used in mower decks.
