In the paper the effect of geometric orientation of bearing shells on damping of forced vibration of journals of an asymmetric rotor has been analysed. Considerable influence of mutual position of the shells, has been confirmed as far as decrement of the vibration amplitude was concerned. The effect of asymmetry oil clearances and journal lengths has been taken into account. The results are shown in appropriate graphs.
