NNF 5007 ADB-2LSV

Double-row full complement cylindrical roller bearings of type NNF with embedded seals, to be supplemented with lubrication

Double row full complement cylindrical roller bearings can be fitted with more rollers and are therefore suitable for very high radial loads as well as medium speeds. The NNF-type bearings have three stops on the double-half inner ring and one stop in the centre of the outer ring for bi-directional positioning on the shaft. Two stop grooves on the outer ring simplify mounting and save axial space.

  • High radial load carrying capacity
  • High radial stiffness
  • Long service life
  • Bidirectional axial positioning of the shaft possible
  • Seals for increased reliability with supplementary lubrication
