putting a journal bearing at each end of the turbine rotor or shaft would be to support it.
it's the thermal expansion in the casing of hp or ip turbine can be noticed by journal or thrust bearing when moving <<
Thrust pads are used to protect the steam turbine rotor from damage due to axial displacement due to axial thrust created by entry of steam in the turbine. generaly the pads clearence is 0.45mm for a bearing size 250mm.

becouse this steam is use repetdly for the turbine
no you can't use dc motor to power hydro turbine ?
to support crankshaft

Machinability for airframes, helicopter,landing gear applications, turbine engine applications....
Turbine thrust bearing active and inactive temperature is the blade in the turbine trust bearing is actual temperature change, which mitigates the active or inactive bearing.
main two type of bearing used in steam turbine:(1)thrust bearing (2)general bearing
bearing journal
Interference between journal bearing to bearing housing is called bearing crush.
hydrodynamics is the study of fluids in motion. Your question needs to be reworded to make more sense.
at the time of turbine start up, the shaft journals are in contact with the white metal of the bearings due to the weight of the rotor. The low pressure of the lubricating oil supply when the set is stationary is insufficient to stop the metal to metal contact between journals and bearing shells. In order to prevent the metal to metal contact between journal and bearing shell during start up, which is damaging in the long term, an oil pocket machined into the bottom shell of the journal bearing is supplied with oil under high pressure. This lifts the shafting system slightly and it floats on a film oil. this is called jacking oil system of turbine
engineering application of fitted bearing
thrust bearing is located on the transmission shaft in the bell housing,sometimes called a throw out bearing. its use is to operate the clutch
