This cylindrical roller bearing carries an inner ring with a smooth raceway (no ribs) and an outer ring with two ribs, allowing free axial displacement between the rings and making it a non-locating bearing suitable for accommodating thermal shaft expansion. Bore diameter is 35.0 mm, outside diameter 80.0 mm, width 31.0 mm, with a net mass of 0.794 kg. The bearing is fitted with a machined M1 cage and reaches a limiting speed of 16400 1/min, with a reference speed of 6600 1/min. Design E indicates an optimized internal geometry for increased load carrying capacity. Radial internal clearance is in the CN (Group N) range, and running accuracy is manufactured to P6 tolerance class, giving tighter dimensional and rotational precision than standard tolerance. The single-row design and rib arrangement make this bearing suitable for radial load support in shaft arrangements where one bearing position must remain axially free while maintaining running accuracy. As an open bearing, it requires external sealing and separate lubrication with grease or oil according to the application's speed and temperature conditions.
