SKF, FAG, NSK and other have plants in China and there is nothing wrong with the quality and are company branded. Timken was/is buying cheaper Chinese and putting them in an Timken box. This is from my own experience of taking some out of hubs that had no brand on the bearing only the box, no COO on either until it was pressed out. On the now visible side there was no company name only China on the outer race, I would say they went to some bother to hide info that may have effected someones buying decision.
There is a big difference in "made by (brand name) in China" and "made in China for (company name)"
