Single-row cylindrical roller bearing with a polyamide cage (TVP2), design type NU with two ribs on the outer ring and a smooth inner ring, allowing free axial displacement between inner and outer ring. Bore diameter is 55.0 mm, outside diameter 100.0 mm, width 21.0 mm, net mass 0.644 kg. Limiting speed is rated at 10000 1/min, reference speed at 5800 1/min. Internal design E provides increased load carrying capacity within the standard envelope dimensions. The non-locating design makes this bearing suitable as a floating bearing, compensating axial shaft expansion caused by thermal growth. Radial internal clearance corresponds to group CN (normal), and running accuracy is held to class P6, giving tighter rotational tolerances than standard P0. The cage guides the rollers separately from the inner ring, allowing the bearing to be mounted with the inner ring pushed onto the shaft independently of the outer ring and housing.
