NNF 5004 ADB-2LSV

Double row full complement cylindrical roller bearing, NNF design, with integral sealing and relubrication feature

Double row full complement cylindrical roller bearings incorporate a maximum number of rollers and are therefore suitable for very heavy radial loads in combination with moderate speeds.

Having three flanges on the two-piece inner ring and one central flange on the outer ring, NNF design bearings can locate the shaft axially in both directions. Two snap ring grooves in the outer ring simplify mounting and save space axially.

  • Very high radial load carrying capacity
  • High radial stiffness
  • Long service life
  • Locate the shaft axially in both directions
  • Sealed for increased reliability, with relubrication feature
