- 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.
- These type of bearings are made in two contact angle levels as shown in Table. They are selected according to sustain axial and moment load.
- Cages are made of pressed steel.
- Some sizes of Double-row Angular Contact Ball Bearing are available with contact seals (2NS) or shields (ZZ).
