SKF 3304A-2RS1TN9/MT33, Double row angular contact ball bearings, with seals or shields, correspond to a pair of single row angular contact ball bearings in a back-to-back arrangement, while requiring less axial space. Depending on the sealing execution, they can operate at high speeds and are more suitable than deep groove ball bearings for supporting large axial forces in both directions.

Bore diameter: 20.0 mm
Outside diameter: 52.0 mm
Width: 22.2 mm
Basic dynamic load rating: 24.5 kN
Basic static load rating: 15.6 kN
