Thrust disk—The thrust disk or thrust runner provides an axial surface for
the thrust bearing pads to ride against. The thrust disk can either can be an inte-
grally machined component, or have interference fit to the rotor (Fig. 7.43).
Bearing housings—Bearing housings contain essential components includ-
ing journal and thrust bearings, overspeed trip hardware, governor drive hard-
ware, and various instrumentation like axial position probes, magnetic pickup
probes, grounding brushes, key phase probes, and bearing load cells (Fig. 7.44).
