Deep groove ball bearing 62304-2RS1 20x52x21 mm
Ball bearings of 623 series medium series with the same bore- and outside diameter are sensibly broader than deep groove ball bearings of the 63 series. They offer a balanced ratio between their radial load carrying capacity, their weight and the admissible speed. Consequently they are versatile.
