There are different types of ISO and manufacturing facilities have different standards than shipping facilities. All bearings are supposed to be made to AFBMA (anti friction bearing manufacturers association) standards. Offshore bearings do not comply with AFBMA in most cases. I can tell you from a bit of experience, that major bearing failures such as this one are due to : misapplication, misdesign, lack of lubrication, and junk! You can purchase the same bearing in this country ..for instance... a 1" pillow block for approx $3.00 for offshore mfg and the same pillow block manufactured in the US will cost you $50.
If in fact they have purchased a lesser quality bearing and in this case the cost of the bearing might be thousands of dollars less, you get what you pay for.
Since I don't know the history of the beginnings of this situation, I wouldn't presume to know what is really wrong.
My question to them would be.....When this was designed and first ran, how long did it run before problems began to arise? Did the manufacturer of the thrust bearing change?
Bearing manufacturers of quality items will warrant their products, but only if they are used properly.
