This is a single row deep groove ball bearing with a bore of 5.0 mm, outside diameter of 19.0 mm, and width of 6.0 mm. It is fitted with metal shields on both sides and a steel sheet metal cage (JN). Net mass is 0.008 kg. The limiting speed is 44500 1/min, with a reference speed of 27000 1/min. Radial internal clearance is in the CN (Group N) range. The metal shields protect the raceway and balls from dust and coarse contamination while retaining the factory grease fill, so no external lubrication is required during service. The CN clearance range corresponds to normal running conditions without preload, suiting applications with standard fits and moderate operating temperatures. The compact envelope dimensions and steel cage design make this bearing suitable for small-diameter shaft support where standard radial load capacity and the stated speed limits are sufficient.
