Cylindrical roller bearing NU315-E-XL-TVP2 is a single-row design with two ribs on the outer ring and a smooth (rib-free) inner ring, allowing axial displacement between the rings — a non-locating bearing. Bore diameter is 75.0 mm, outside diameter 160.0 mm, width 37.0 mm, and net mass is 3.244 kg. The polyamide cage is coded TVP2, radial internal clearance is CN (Group N), and running accuracy is in class P6. Limiting speed is 5900 1/min, reference speed 4150 1/min. Because the outer ring can move axially relative to the inner ring, this bearing accommodates thermal expansion or shaft length changes without inducing axial load, making it suitable as a floating bearing in a shaft arrangement paired with a locating bearing on the opposite side. The P6 running accuracy supports applications requiring tighter rotational precision than standard tolerance, while the smooth inner ring design allows the rollers and outer ring to be mounted or removed independently of the inner ring, simplifying assembly on the shaft.
