SKF LNNU 4930/SPC3 Inner ring for double row cylindrical roller bearings, NNU design

Inner rings for cylindrical roller bearings in the NNU series are supplied as separate components. This enables full interchangeability of inner rings while maintaining the radial clearance. An inner ring can also be combined with an outer ring with a roller and cage assembly to create a complete bearing. Having no flanges, inner rings for NNU series bearings can accommodate axial displacement in both directions.
