Approx how many miles do you get on a set of bearings?

If you ever look at a bearing diagnosis chart, you will see pictures of bearings that are on their way to failure... The interesting thing is just how many different causes are listed.
Everything from Improper setup, lubrication, overloading, shock loading (rough roads). and others I cannot recall at the moment. At any rate, such a chart and its pics can determine pretty much what went wrong. Not all of the causes are attributable to improper setup or lubrication.

I doubt it would be much help though after a failure has occurred.

As for the expense, IF you got some american made bearings, it is justified. The chinese ones are really cheap.... I am not going to get into the quality aspect, other than to say it appears to be inconsistent. Many bad reports, and some good ones.
