This is a single row deep groove ball bearing with a steel sheet metal cage (JN), designed with a narrow cross-section relative to its bore. Bore diameter is 45.0 mm, outside diameter 75.0 mm, and width 10.0 mm, giving a net mass of 0.16 kg. The limiting speed is rated at 13100 1/min, with a reference speed of 6900 1/min, and the bore type is coded Z. The radial internal clearance falls in the CN (Group N) range, which is the standard clearance class suitable for typical fit and temperature conditions without requiring special adjustment. The narrow width combined with the steel cage makes this bearing suited for applications where axial space is limited but radial load capacity at this bore size is still required. As a single row deep groove design, it accommodates predominantly radial loads along with limited axial loads in both directions, and the standard clearance allows for straightforward mounting without preloading considerations.
