What type of bearing is most generally used as an independent main thrust block on merchant ships?

Question 1 of 27070

What type of bearing is most generally used as an independent main thrust block on merchant ships?

🔍 Key Concepts

• Types of thrust bearings used on merchant ship propulsion shafts • Difference between journal bearings (for radial loads) and thrust bearings (for axial loads) • Features of a bearing that make it suitable as an independent main thrust block for large power transmission

💭 Think About

• Which design is best for carrying axial (thrust) load from a propeller shaft over long periods with changing sea conditions? • Which option allows individual surfaces to adjust to misalignment and maintain an oil film under heavy thrust? • Which of these is most commonly mentioned in marine engineering texts as the standard main thrust block on modern merchant ships?

✅ Before You Answer

• Identify which listed bearing type is specifically designed for axial thrust, not just radial support • Consider which construction allows multiple pads or surfaces to share the load and self-align under heavy thrust • Ask: in a large slow-speed diesel merchant ship, which type do textbooks typically show as the main thrust bearing arrangement?
