What statement is true concerning the purpose of an independent main thrust bearing where used?

🔍 Key Concepts

• Difference between axial thrust (along the shaft) and radial thrust (sideways to the shaft) • What forces a main thrust bearing is specifically designed to take from the propeller • How propeller thrust is ultimately passed from the shaft to the ship’s hull

💭 Think About

• Is the propeller mainly pushing/pulling the ship forward and backward, or pushing the shaft sideways? Which type of load is that? • Which bearings in a propulsion system usually keep the shaft centered (radial support), and which bearing handles the push from the propeller? • Think about what would happen to the engine and reduction gear if there were no thrust bearing to take the propeller’s push — where would that force go?

✅ Before You Answer

• Identify clearly whether a main thrust bearing is for axial or radial loads • Decide whether its role is only to align/support the shaft or also to pass thrust into the ship’s structure (hull) • Eliminate any choice that confuses the role of line/shaft bearings (supporting radial loads) with that of a thrust bearing (taking propeller push)

What statement is true concerning the purpose of an independent main thrust bearing where used?

The main purpose of the main thrust bearing is to absorb radial thrust and maintain the shaft in proper radial alignment.

The main purpose of the main thrust bearing is to absorb axial thrust and maintain the shaft in proper axial alignment.

The main purpose of the main thrust bearing is to absorb axial thrust and to transmit the axial thrust developed by the propeller to the ship's hull.

The main purpose of the main thrust bearing is to absorb radial thrust and to transmit the radial thrust developed by the propeller to the ship's hull.
