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.

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.
