This cylindrical roller bearing is a single-row design with two ribs on the outer ring and one rib on the inner ring, configured as a semi-locating bearing (type NJ). Bore diameter is 55.0 mm, outside diameter 100.0 mm, width 21.0 mm, net mass 0.67 kg. The limiting speed is 10000 1/min, with a reference speed of 5800 1/min. The polyamide cage (TVP2) and reinforced internal design (E) allow higher load carrying capacity within the same envelope dimensions. Radial internal clearance falls in the CN (Group N) range, suitable for standard fit conditions without preload requirements. The semi-locating configuration allows axial displacement of the inner ring relative to the outer ring, accommodating thermal expansion of the shaft while the single rib on the inner ring maintains guidance. This bearing arrangement is intended for radial load support where axial float on one side is required.
