SKF double row deep groove ball bearing

SKF 4312ATN9, Double row deep groove ball bearings correspond, in their design and operation, to a pair of single row deep groove ball bearings. They are robust in operation, requiring little maintenance, can operate at high speeds and accommodate radial and axial loads in both directions. They are slightly wider than single row bearings of the same bore and outside diameter but have a considerably higher load carrying capacity.

  • Bore diameter: 60.0 mm
  • Outside diameter: 130.0 mm
  • Width: 46.0 mm
  • Basic dynamic load rating: 112.0 kN
  • Basic static load rating: 98.0 kN
