This single row cylindrical roller bearing has a bore diameter of 40.0 mm, an outside diameter of 90.0 mm, and a width of 23.0 mm, with a net mass of 0.654 kg. The outer ring carries two ribs and the inner ring one rib, forming a semi-locating bearing of type NJ with reinforced internal design E. The cage is executed in polyamide as TVP2, and the radial internal clearance is C4 (Group 4). Limiting speed is rated at 10900 1/min, with a reference speed of 7100 1/min. The single rib on the inner ring and two ribs on the outer ring allow the bearing to carry radial loads while permitting axial displacement in one direction, making it suitable as a floating bearing position. The C4 internal clearance compensates for thermal expansion during operation, and the polyamide TVP2 cage supports smooth roller guidance at the stated speed ratings. The E design increases load carrying capacity within the same envelope dimensions, and the open construction requires external sealing and lubrication arrangements to be provided by the housing.
