This deep groove ball bearing carries radial and moderate axial loads in a single row of balls running between an inner ring with 45.0 mm bore and an outer ring of 75.0 mm outside diameter, giving a width of 16.0 mm and a net mass of 0.24 kg. The bearing is fitted with steel sheet metal shields on both sides (2Z) and uses a steel sheet metal cage (JN), permitting a limiting speed of 11200.0 1/min and a reference speed of 9700.0 1/min. Radial internal clearance is CN (Group N), suitable where standard running clearance is required without additional preload considerations. The shields protect the raceway and balls from coarse contaminants while retaining the factory-applied grease, so this bearing is intended for applications where relubrication access is limited and moderate speeds within the stated limiting and reference values are expected.
