This single row cylindrical roller bearing is built to type NU, with two ribs on the outer ring and a smooth inner ring raceway, allowing free axial displacement between the two rings. Bore diameter is 70.0 mm, outside diameter 110.0 mm, width 20.0 mm, and net mass is 0.678 kg. The bearing runs on an M1 cage and is manufactured to running accuracy class P6. Limiting speed is rated at 12300 1/min, with a reference speed of 5500 1/min, and radial internal clearance falls in the CN (Group N) range. The non-locating design lets the inner and outer rings move axially relative to each other, so this bearing accommodates thermal expansion of the shaft while carrying only radial load. The P6 accuracy class supports applications requiring tighter running tolerances than standard P0, and the CN clearance range is suited for typical mounting conditions without added preload. The M1 cage guides the rollers at the row and is designed for the speeds stated above.
