1. The method of controlling the axial thrust on a thrust bearing assembly of a rotating machine wherein said thrust bearing assembly comprises a rotating component and a nonrotating component, one face of said rotating component and one face of said non-rotating component being in opposing relationship with each other, wherein a lubricant is forced in operation between the opposed faces of said components forming a first zone of pressure between said faces maintaining them separated and transmitting thrust load between them;

  • and wherein there is a balancing means operable to apply a desired end thrust to one of said components to adjust the thrust forces on said bearing;

    said method comprising the steps of determining from time to time the axial thrust on said assembly by monitoring the pressure of said lubricant in said first zone and operating said balancing means in accordance with the axial thrust determination to produce a desired aggregate thrust on said bearing assembly.
