A thrust bearing is designed to accomplish...

🔍 Key Concepts

• Understand what thrust is in a marine propulsion system (which way the force is going) • Know the role of a thrust bearing in relation to the propeller shaft and the ship’s structure • Distinguish between components that handle propeller thrust, engine power transmission, and vibration/shock absorption

💭 Think About

• Ask yourself: Where does the propeller’s pushing force ultimately need to go so the vessel actually moves? Through which part is that force carried into the hull? • Which component’s main job is to carry axial force (along the shaft) rather than just support the shaft radially (up/down) or absorb vibration? • Look at each option and decide: Is this describing force from propeller to ship, from engine to propeller, or just damping movement/shock?

✅ Before You Answer

• Identify which option mentions transmitting propeller thrust into the vessel’s structure, not just between machinery parts • Eliminate choices that mainly describe vibration or shock absorption rather than continuous axial load carrying • Make sure the function you pick matches a bearing that is mounted to the hull/structure to take axial load from the shaft

A thrust bearing is designed to accomplish which action?

To transmit the thrust of the propeller to the vessel

To absorb the shock of wave pressure at the bow

To transmit the thrust of the engine to the propeller

To be placed between the engines and the foundation to absorb the vibration
