Hmmm, cheap cheese bearings are not really the answer in my opinion.


Making a rolling element bearing is not that difficult with modern machinery, where China and India fall down is in the black art of steel making eg manganese inclusions etc. As their steel makers improve their bearing life will improve. With an inclusion just below the surface in a ball or roller track the surface strength at that point is too low and once it cavitates the end of the bearing follows shortly. Sort that out and life span will be equivalent.

They will get better just as the Japanese did, question is when and which maker to trust that they has their steel supplier sorted out.
