SKF double row full complement cylindrical roller bearing, NNCF design

SKF NNCF5028CV, 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 inner ring and one flange on the outer ring, NNCF design bearings can accommodate limited axial displacement in one direction. A retaining ring in the outer ring holds the bearing together. The retaining ring should not be loaded axially during operation.

  • Bore diameter: 140.0 mm
  • Outside diameter: 210.0 mm
  • Width: 95.0 mm
  • Basic dynamic load rating: 809.0 kN
  • Basic static load rating: 1370.0 kN
