SKF/FAG bearings | Adventure Rid
I sold bearings for many years. IMHO, SKF are arguably the best, but to be fair there isn't a great deal of difference in quality between the various "better" brands these days. My personal preference is still SKF, but any reputable brand such as NTN, NSK, NACHI, KOYO and FAG will be of consistently excellent quality.
