This single row cylindrical roller bearing carries the bore/outside diameter/width of 80.0/170.0/39.0 mm and a net mass of 3.812 kg. The outer ring has two ribs while the inner ring is smooth (0 ribs), design type NU, which makes it a non-locating bearing allowing axial displacement between inner and outer ring. The cage is a glass-fibre reinforced polyamide cage, type TVP2, and the design suffix E indicates a reinforced internal design with increased load rating. Running accuracy is in tolerance class P6, radial internal clearance is CN (Group N). Limiting speed is 5500 1/min and reference speed is 4100 1/min. The non-locating design lets the bearing accommodate axial shaft displacement without inducing axial load, which is useful where thermal expansion of the shaft has to be compensated. Standard P6 running accuracy combined with CN internal clearance suits applications requiring precise radial guidance under moderate speeds. The polyamide cage (TVP2) is suited to the specified reference and limiting speed range, and being an open bearing without integrated seals or shields, it requires external sealing and a separate lubrication supply, either grease or oil, matched to the operating speed and temperature.
