This deep groove ball bearing carries radial and light axial loads on a single row of balls, with a bore diameter of 17.0 mm, outside diameter of 30.0 mm, and width of 7.0 mm. It has a net mass of 17.0 g and uses a steel sheet metal cage (JN). The bearing is fitted with seals on both sides (2RSR) and reaches a limiting speed of 12700 1/min. The radial internal clearance falls in group CN, suitable for standard fit conditions without excessive play. Integrated seals keep grease in place and block contamination, so the bearing runs sealed for life without maintenance. Its compact cross-section and steel cage keep mass low while maintaining stable ball guidance at the rated speed.
