Duplex angular contact ball bearings

  Duplex angular contact bearings are a matched set of angular contact bearings mounted in pairs. Depending onthe duplex type, they can handle combined radial and axial loads in either one or two directions. The inner andouter ring raceways are offset to each other, resulting in a shoulder on the inner raceway rings. This asymmetricalinternal design works well with contact angles between 15 and 40 degrees. Duplex angular contact bearings withlarger contact angles are ideal for higher axial loads and lower radial loads. Certain duplex angular contact bearings are designed to withstand even larger angles. Depending on the application, the relative proportions ofthe inner and outer races should match the desired contact angle.
