5309, NSK, double-row angular contact ball bearings, Bore diameter: 45 mm; Outside diameter 100 mm; Width 39.7 mm.

NSK 5309 bearing is basically a back-to-back of two single-row angular contact ball bearings, but their inner and outer rings are each integrated into one. So axial loads in both directions can be sustained, and the capacity to sustain moments is good.
