This single row cylindrical roller bearing supports radial loads while allowing free axial displacement of the shaft within the bearing, since the outer ring carries two ribs and the inner ring runs smooth without ribs (type NU). Bore diameter is 85.0 mm, outside diameter 180.0 mm, width 41.0 mm, and net mass is 4.475 kg. Limiting speed is rated at 5200 1/min, with a reference speed of 3900 1/min. The polymer cage (TVP2) guides the rollers, and the reinforced E design increases load capacity within the same envelope dimensions. Radial internal clearance is C3, wider than standard, compensating for thermal expansion under load and allowing correct operating clearance once the bearing reaches working temperature. Running accuracy conforms to P6, suitable for applications requiring tighter dimensional and rotational tolerances than standard P0. As a non-locating bearing, it accommodates axial shaft movement while the outer ring ribs retain radial guidance, making it suitable for mounting positions where thermal shaft growth or axial free play needs to be absorbed.
