SKF 3203ATN9, Double row angular contact ball bearings correspond, in their design and operation, to a pair of single row angular contact ball bearings in a back-to-back arrangement, while requiring less axial space. They can operate at high speeds and are more suitable than deep groove ball bearings for supporting large axial forces in both directions.

Outside diameter: 40.0 mm
Width: 17.5 mm
Basic dynamic load rating: 14.3 kN
Basic static load rating: 8.8 kN
