This single-row cylindrical roller bearing carries the outer ring ribs while the inner ring runs smooth, allowing axial displacement between the two rings and making it a non-locating bearing. Bore diameter is 70.0 mm, outside diameter 150.0 mm, width 35.0 mm, net mass 3.037 kg. Limiting speed reaches 8200.0 1/min, reference speed 4500.0 1/min, radial internal clearance is in group CN, and the cage is executed as M1. The E design provides an optimized internal geometry for higher load carrying capacity. Because the inner ring has no ribs, the bearing accommodates axial shaft movement without transmitting axial load, which suits applications where the shaft expands or shifts relative to the housing. Running accuracy corresponds to class P6, giving tighter dimensional and rotational tolerances than standard class. The CN clearance group is suited for standard operating conditions, and the M1 cage supports stable roller guidance at the stated speed ratings.
