Interestingly, I just reverse-engineered seven Toyota automotive wheel bearings for a client of mine. They wanted to benchmark the quality of the bearings. One was even made in the USA by Koyo. Another was a Timken brand. All bearings showed good quality with nothing lacking in the metallurgy.

China still hasn't caught up with bearing quality, but it won't be long until their quality is right up there with the rest of the world. If fact, I'm beginning to see world class quality from the steel they supply.
