This single-row cylindrical roller bearing has a bore of 25.0 mm, outside diameter of 52.0 mm, and width of 18.0 mm, with a net mass of 0.178 kg. The outer ring carries 2 ribs while the inner ring is smooth (0 ribs), making it a non-locating (NU type) design that allows axial displacement between inner and outer ring. It is fitted with an M1 cage and built to the E design for increased load rating. Limiting speed is 25500 1/min, with a reference speed of 9600 1/min, and running accuracy corresponds to class P6. The floating design allows the bearing to compensate for axial shaft expansion without inducing additional load, making it suitable as a non-locating bearing in a shaft-bearing arrangement. Radial internal clearance C3 (Group 3) permits increased clearance, useful where thermal expansion during operation is expected. The M1 cage supports stable roller guidance at the given speed range, and P6 accuracy ensures tighter dimensional and running tolerances than standard class for precise radial guidance.
