This single row cylindrical roller bearing consists of an outer ring with 2 ribs and a smooth inner ring with no ribs, type NU, allowing free axial displacement between the ring and rollers, making it a non-locating bearing. Bore diameter is 85.0 mm, outside diameter 150.0 mm, width 36.0 mm, and net mass is 2.73 kg. The bearing is fitted with an M1 cage and features the E design for increased load capacity. Limiting speed is 8300.0 1/min, with a reference speed of 3300.0 1/min. The radial internal clearance falls within CN (Group N), suitable for standard operating conditions without significant preload or excess play. Running accuracy is held to P6 tolerance class, supporting precise shaft positioning where rotational accuracy matters. As a non-locating bearing, it accommodates axial expansion of the shaft relative to the housing, which is useful where thermal growth or shaft length variation must be compensated without introducing axial constraint.
