🔍 Key Concepts

• Understand what a Kingsbury thrust bearing does in a propulsion shaft line • Know which component actually receives thrust from the propeller shaft and how it is passed into the ship’s structure • Differentiate between thrust collar, thrust shoes (pads), and bearing housing roles

💭 Think About

• Start from the propeller: which shaft carries the propeller’s push, and what is the very first part it presses against inside the thrust bearing? • Ask yourself: which part is fixed to the rotating shaft, and which parts are stationary and connected to the ship’s hull? • Visualize the load path: from rotating shaft to intermediate parts to the static structure that ultimately pushes the ship forward.

✅ Before You Answer

• Identify which item in each choice is the rotating component (connected to the shaft) and which are stationary support components • Confirm that thrust shoes (pads) transmit load between the rotating collar and the stationary housing, not the other way around • Make sure the sequence starts from the correct shaft (engine vs. propeller shaft) that actually carries the propeller thrust back toward the ship.
