SKF single row full complement cylindrical roller bearing, NJG design

NJG2308VH, Single row full complement cylindrical roller bearings are designed to accommodate very high radial loads in combination with moderate speeds. The bearings incorporate a maximum number of rollers as they are not equipped with a cage. Having two integral flanges on the outer ring and one on the inner ring, NJG design bearings can accommodate axial displacement in one direction. A self-retaining roller complement enables the bearing components to be separated, which facilitates mounting and enables the bearing components to be interchanged.

  • Bore diameter: 40.0 mm
  • Outside diameter: 90.0 mm
  • Width: 33.0 mm
  • Cage: Without
  • Radial internal clearance: CN
