  • Thrust bearings | The steam turbine

    Hydrodynamic thrust bearings transmit axial load by floating the rotor on a thin film of fluid (Fig. 1) and are often referred to as fluid film bearings.A suitable lubricant must always be present between the rotating collar and thrust bearing surface for hydrodynamic bearings to operate safely and efficiently.

  • (PDF) Thrust bearing monitoring of vertical hydro

    A down-thrust bearing, thrust runner, and up-thrust bearing are shown in Fig. 12.15.The down-thrust bearing in 400 series seal can carry 6000 lbs of thrust at 3500 RPM at oil temperatures up to 200°C (392°F).The up-thrust bearing is designed for much smaller loads since a special set of circumstances must occur to place the seal shaft into up thrust.

  • Gas and Steam Turbine Bearings for Thrust and

    2020-10-21 · On a turbine the active thrust bearing is the only one which takes the wear so this is the one which has to have accurate protection. So we set the channel zero position voltage to the voltage we note on the channel when we start the unit up after we install it. In this case we would insert the number -11.6 volts, and because we configure the ...

With the bearings discussed pre­ viously, any misalignment of the bearing to the thrust collar will act to decrease the load capacity of the bearing. This is because one sector of the bearing will be loaded higher than others resulting in a 'weak link' that would be the first area to fail, quickly followed ...
