If you REALLY want the best, go get some high quality super precision bearings...but hold on to your hat when you see what they cost!
The K.I.S.S. pricipal works here best as in most instances....
The price of a bearing means nothing on it's "expected" life...and in this case, "ultra precision" class bearings will simply destroy themselves in no time. Tossing money out the door 2x for the effort.
The application we have here is designed for a bearing with a really low precision index,
on purpose, and this in fact leads to long operating life.
You can get a p.o.s. bearing from any manufacturer also, so understand that any NEW bearing may not live as long as the one you just replaced.
As for the Chinese and all the other middle eastern manufactured products, they are all simply equal. I have had the best luck with NTN, FAG, SKF, but have had those very same high end parts fail also.....it's a coin toss.
