Q

The axial position of a turbine rotor is controlled by the thickness of the __________.

🔍 Key Concepts

• Function of a thrust bearing in locating a rotor axially • Difference between axial location (thrust) and radial support (journal bearings) • Which turbine components are mainly for sealing, not positioning

💭 Think About

• Ask yourself: Which part of the bearing assembly is specifically adjusted to move the rotor forward or aft along its shaft? • Which options relate to radial clearance versus axial clearance? • Which component’s thickness can be changed during assembly to fine‑tune the rotor’s fore‑and‑aft (endwise) position?

✅ Before You Answer

• Identify which choices are directly part of the thrust bearing axial adjustment mechanism. • Eliminate any option that primarily supports radial load instead of axial load. • Eliminate any option whose main purpose is steam or gas sealing, not rotor positioning.
