This deep groove ball bearing carries radial and moderate axial loads in a single-row configuration with a bore diameter of 12.0 mm, outside diameter of 30.0 mm, and width of 8.0 mm. It weighs 27.2 g and is fitted with steel shields on both sides (2Z), combined with a pressed steel sheet metal cage (JN). The limiting speed is 32500 1/min, with a reference speed of 25000 1/min. The steel shields protect the raceway and balls from dust and coarse contamination while retaining the internal grease fill, making this bearing suited for applications where relubrication access is limited. Radial internal clearance is CN (Group N), the standard clearance range, providing predictable running behavior under normal thermal and load conditions. The pressed steel cage keeps the design lightweight and compatible with the stated speed ratings, and the shielded, non-contact seal type allows the bearing to run at higher speeds than contact-seal variants while still offering basic protection against ingress.
