SKF NU228ECML bearing

Bearing NU 228 ECML Bearing NU 228 ECML

The major players, INA/FAG, SKF and Timken all manufacture in China and have top notch quality control, so those bearings should be the same quality as those made here and in Europe. Timken is the only major I know of that imports Chinese bearings, so if you see an SKF or FAG with Chinese markings on it, be suspect.
