This cylindrical roller bearing accommodates axial displacement between shaft and housing, functioning as a non-locating bearing due to its NU design with two ribs on the outer ring and a smooth inner ring. Bore diameter is 180.0 mm, outside diameter 280.0 mm, width 46.0 mm, and net mass 10.4 kg. The single-row roller set runs in an M1 cage, with limiting speed of 4500.0 1/min and reference speed of 2550.0 1/min. Radial internal clearance corresponds to CN (Group N), suitable for standard fit conditions without preload requirements. Running accuracy is manufactured to P6 class, allowing tighter shaft and housing tolerances than standard P0. The M1 cage construction supports stable roller guidance at the stated speed range, while the free inner ring allows the bearing to compensate for axial shaft movement caused by thermal expansion or manufacturing tolerances.
