The rotor of every turbine must be positioned radially and axially by what?

The rotor is positioned radially and axially by bearings. Bearings provide the support and stiffness needed to keep the rotor centered in the bearing housing (radial position) and to resist thrust forces that try to move the rotor along the shaft (axial position). Proper lubrication, clearances, and any preload in the bearings help maintain that position during operation, absorbing loads and reducing wear. Gears transmit torque, shafts carry power, and supports are structural; none of these actively define and maintain the rotor’s precise radial and axial location the way bearings do.
