This cylindrical roller bearing has a single row of rollers guided by a polyamide cage (TVP2), with two ribs on the outer ring and a smooth (rib-free) inner ring, following the NU design. Bore diameter is 40.0 mm, outside diameter 80.0 mm, width 23.0 mm, and net mass 0.478 kg. Limiting speed reaches 12500 1/min, reference speed 6300 1/min, radial internal clearance is CN (Group N), and running accuracy is class P6. The E design indicates an optimized internal geometry for increased load rating. The smooth inner ring allows axial displacement between inner and outer ring, making this a non-locating bearing suitable for compensating axial shaft expansion within its own position. The polyamide cage supports smooth roller guidance and permits favorable operation at higher speeds within the stated limiting and reference values. Normal radial internal clearance (CN) combined with P6 running accuracy suits applications requiring standard fit tolerances and improved rotational precision. As an open bearing, lubrication and sealing must be provided externally, and grease or oil lubrication should be selected according to the operating speed range.
