🔍 Key Concepts

• Propeller shaft thrust bearing arrangement and how axial loads are transmitted to the hull • Difference between radial (sleeve) bearings and thrust bearings • Names of the individual parts inside a Kingsbury-type thrust bearing, especially the pads that contact the collar

💭 Think About

• Look at the direction of load that the part labeled 6 is designed to carry: is it supporting the shaft radially (around its circumference) or taking axial push from the propeller? • Which component actually touches the rotating collar on the shaft to absorb axial force, and what is that piece commonly called in a thrust bearing? • Compare where item 6 is mounted relative to the shaft and collar: does its shape suggest a continuous sleeve, a resilient spring support, a collar on the shaft, or individual pads arranged around the collar?

✅ Before You Answer

• Verify which part in the illustration is the collar attached to the shaft and which is the stationary support structure • Confirm whether item 6 is a separate segment arranged in a circle, or a full ring/sleeve around the shaft • Make sure you can distinguish between a radial sleeve bearing surface and the segments that take axial thrust before choosing your answer
