Deep groove ball bearing 62311-2RS1 55x120x43 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.
