Single row radial ball bearing with a narrow cross-section, bore diameter 150.0 mm, outside diameter 225.0 mm, width 24.0 mm. Net mass is 3.17 kg. The cage is a pressed steel sheet type (JN), and radial internal clearance is standard CN (Group N). Limiting speed is 4050 1/min, with a reference speed of 3100 1/min, giving the bearing a moderate speed capability relative to its size. The thin-section design combined with the standard CN clearance suits applications requiring reduced radial dimensions while maintaining stable radial guidance under moderate loads. The steel sheet metal cage keeps rolling element spacing consistent and supports smooth operation at the stated speed range. As the bore type is Z (cylindrical, no special bore modification noted), mounting follows standard shaft fit practices, and lubrication should be selected according to the actual operating speed and temperature conditions within the given limiting and reference speed values.
