This single-row cylindrical roller bearing has a bore diameter of 85.0 mm, an outside diameter of 180.0 mm, and a width of 41.0 mm, with a net mass of 5.139 kg. The outer ring carries 2 ribs while the inner ring is smooth (0 ribs), design type NU, allowing axial displacement between inner and outer ring so the bearing functions as a non-locating bearing. It uses an E design with an M1 cage, radial internal clearance C3, and running accuracy to P6, with limiting speed of 6800.0 1/min and reference speed of 3800.0 1/min. The smooth inner ring and ribbed outer ring construction lets this bearing accommodate axial shaft movement while carrying radial loads, making it suitable as a floating bearing position on a shaft. The M1 cage supports stable roller guidance at the stated speed values, C3 internal clearance compensates for thermal expansion during operation, and the P6 running accuracy provides tighter dimensional and rotational tolerances than standard tolerance class for applications requiring improved shaft rotation precision.
