This single row cylindrical roller bearing, type NJ, carries a bore diameter of 80.0 mm, outside diameter of 170.0 mm and width of 58.0 mm, with a net mass of 5.699 kg. The outer ring has 2 ribs and the inner ring has 1 rib, giving a semi-locating design that allows axial displacement in one direction while guiding the shaft in the other. The polyamide cage (TVP2) runs with the reinforced E design, supporting a limiting speed of 5500 1/min and a reference speed of 3450 1/min. The radial internal clearance is C3 (Group 3), which compensates for interference fits and thermal expansion during operation. The semi-locating arrangement makes this bearing suitable for shaft positions where axial guidance is needed only on one side, while the non-locating side of the assembly can be handled by another bearing. Lubrication and mounting should follow standard practice for cylindrical roller bearings with an E design and TVP2 cage.
