This single-row cylindrical roller bearing carries two ribs on the outer ring and one rib on the inner ring, forming a semi-locating configuration that allows axial displacement in one direction while restraining it in the other. Bore diameter is 70.0 mm, outside diameter 150.0 mm, width 51.0 mm, and net mass 4.05 kg. The E design provides an optimized internal geometry for increased load carrying capacity, and the bearing runs with a polyamide cage (TVP2) and radial internal clearance CN (Group N). Limiting speed is rated at 6300 1/min, with a reference speed of 3800 1/min. The semi-locating design lets this bearing take up axial loads in one direction while accommodating shaft expansion on the opposite side, which is useful where thermal growth along the shaft must be compensated without introducing axial preload. The CN clearance suits standard mounting conditions, and the separable inner and outer rings simplify installation and removal on the shaft and in the housing. The TVP2 cage supports stable roller guidance at the stated speed ratings, making the bearing suitable for radial loads where controlled axial positioning is required.
