SKF front wheel bearing hub assemblies - any good? - Bob .
1. They are wrong. They market OEM and aftermarket, each has different performance criteria. They may have dropped what they called "value grade", but they are still marketing aftermarket hub bearings, and are working with China to source parts and hopefully source complete bearings.
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.

Bearings extend the working life of wheels, pulleys, and other rotating parts by reducing friction and enabling parts to move smoothly. Also called slewing rings or slewing bearings, they are installed between two surfaces to keep parts aligned and support axial and radial loads.
