Double-row Angular Contact Ball Bearings
- The construction of this ball bearing is similar to mounting two single row angular ball bearings back to back(DB).
- Capacities of double row ball bearing is less than single row since few balls can be inserted per row.
- This bearing type can sustain radial, moment and bi-directional axial loads.
