SKF/FAG bearings | Adventure Rid
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.

Ball bearings are used with applications that have high axial loads and low-to-moderate radial loads. Mounted bearings (bearing units) have a bearing inside a housing unit to ensure a secure fit and mount. Sleeve and clip bearings support high loads, have no moving parts, and require lubricant to allow the shaft to turn smoothly.
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.

Certain brand is good in particular type of bearings, for example: SKF is good in spherical roller ( their invention), Timken is good in tapered roller (also their invention), Schaeffler group is good in needle rollers and NSK is good in precision ball bearings. it's difficult to single out best ball bearings brand nowadays.
