Deep groove ball bearing 6203-2RS 17x40x12 mm, contact seal
Ball bearings of the 62 light series support relatively high radial load-ratings despite their reduced weight. Compared to deep groove ball bearings of the 63 and 64 series they require a smaller installation space at the same inside diameter by their relatively small outside diameter and allow slightly higher speeds furthermore
