✔ High radial load capacity: The cylindrical roller format provides a large contact area, enabling strong radial load support.
✔ Axial displacement allowed: The NU-type design allows axial movement of the shaft relative to the housing, making it suitable for floating bearing arrangements in applications where shaft expansion or misalignment occurs.
✔ Smooth, low-friction operation: Optimized internal geometry (roller profile, raceway finish) helps reduce friction and promote efficient, stable motion.
✔ Separable inner and outer rings: The inner ring + roller + cage assembly is separable from the outer ring, simplifying mounting and maintenance.
✔ Suitable for moderate to high speeds: With its width and precision design, it is appropriate for demanding industrial drives.

Industrial equipment where radial load is dominant and axial displacement must be accommodated (floating bearing setups)
The SKF NU 313 is a high-precision single-row cylindrical roller bearing, engineered to support heavy radial loads while permitting axial movement of the shaft in both directions. With the NU-type configuration (two integral flanges on the outer ring, no flange on the inner ring), it functions as a floating bearing—ideal for applications where axial expansion or displacement of the shaft must be accommodated.
