This single row cylindrical roller bearing has a bore of 40.0 mm, an outside diameter of 90.0 mm, a width of 23.0 mm and a mass of 0.763 kg. It is built as a non-locating bearing of type NU, with two ribs on the outer ring and a smooth inner ring, allowing free axial displacement between rings within the bearing. The E design gives an increased roller load rating for the given envelope. The cage is designated M1, radial internal clearance is C3 (Group 3), and running accuracy corresponds to class P6. Limiting speed is 14200 1/min, reference speed is 7100 1/min. Because the outer ring can move axially relative to the inner ring, this bearing is suited for use as a non-locating support on a shaft, absorbing thermal expansion and length changes without introducing axial preload. The C3 clearance compensates for interference fits and thermal growth, while the M1 cage supports stable roller guidance at the stated speeds. P6 running accuracy provides tighter dimensional and running tolerances than standard class, suitable where reduced radial runout is required.
