Question 1 of 27070

For a large main propulsion turbine, the most commonly used turbine thrust bearing is the __________.

🔍 Key Concepts

• Turbine thrust bearing purpose – what force does it absorb and in what direction? • Difference between radial bearings (supporting the shaft) and thrust bearings (taking end‑thrust/axial load). • Common marine main propulsion thrust bearing design used with large, slow‑turning shafts.

💭 Think About

• Ask yourself: which option actually describes a type of thrust bearing rather than just a general bearing or wheel? • Which design gives several small surfaces that can individually adjust to carry heavy axial loads and maintain an oil film? • Eliminate any options that sound like they mainly support the shaft radially instead of taking axial (endwise) thrust.

✅ Before You Answer

• Be sure the choice you pick is specifically associated with axial (endwise) thrust, not radial support. • Check which terms refer to bearing construction versus something that sounds like part of the turbine rotor itself. • Verify which design is known for multiple separate pads/shoes that tilt to form a wedge‑shaped oil film under heavy load.
