This cylindrical roller bearing carries a single row of rollers guided in an M1A cage, with two ribs on the outer ring and a smooth (rib-free) inner ring raceway, corresponding to design type NU. Bore diameter is 25.0 mm, outside diameter 62.0 mm, width 17.0 mm, and net mass 0.269 kg. The limiting speed is 21500 1/min, with a reference speed of 10100 1/min. Radial internal clearance is C3 (Group 3), and the design follows the E series with running accuracy to P6. Because the inner ring has no ribs, the bearing functions as a non-locating type, allowing axial displacement between the inner and outer rings and compensating for shaft expansion or minor misalignment along the axis. The C3 clearance suits applications with elevated operating temperatures or interference fits that reduce internal clearance during assembly. The P6 running accuracy supports applications requiring tighter dimensional and rotational tolerances than standard class. The M1A cage design, combined with the E-series internal geometry, allows a higher roller count for increased radial load capacity within the same envelope dimensions.
