This cylindrical roller bearing accommodates axial displacement between shaft and housing, functioning as a non-locating bearing. It is single row, type NU, with two ribs on the outer ring and a smooth (rib-free) inner ring, allowing free axial movement of the inner ring relative to the outer ring. Bore diameter is 80.0 mm, outside diameter 170.0 mm, and width 58.0 mm, with a net mass of 5.746 kg. The bearing runs to a limiting speed of 5500 1/min and a reference speed of 3450 1/min. It uses a polyamide cage (TVP2) and features the reinforced E design for increased load carrying capacity. Radial internal clearance is CN (Group N), suitable for standard operating conditions without preload requirements. Running accuracy corresponds to tolerance class P6, providing tighter dimensional and geometric control than standard tolerance for applications requiring accurate shaft guidance. The non-locating design and smooth inner ring make this bearing suitable for the floating position in a bearing arrangement, where it compensates for thermal expansion or shaft misalignment along the axial direction while carrying radial loads.
