This deep groove ball bearing carries radial and moderate axial loads in a thin-section, single row design with a bore of 10.0 mm, outside diameter of 19.0 mm, and width of 5.0 mm. The bearing is fitted with metal shields on both sides (2Z) and uses a steel sheet metal cage (JN). Net mass is 0.005 kg, with a limiting speed of 46000 1/min and a reference speed of 27500 1/min. Radial internal clearance falls in group CN (normal), suitable for standard fit conditions without added preload requirements. The metal shields protect the raceway and balls from dust while allowing operation with grease lubrication already present in the shielded space. Given its compact cross-section and low mass, this bearing suits applications requiring tight radial space and high rotational speed capability within the limits stated above.
