🔍 Key Concepts

• Kingsbury thrust bearing construction – relationship between thrust shoes, leveling plates, and base ring • Difference between upper and lower leveling plates and what each one rests against • How axial load is transmitted from the shaft collar, through the shoes, to the foundation

💭 Think About

• Visualize the stack-up from the shaft outward: thrust collar → shoes → upper leveling plates → lower leveling plates → base ring. Which element is physically in contact with the upper plates? • Ask yourself: what must be allowed to move slightly to equalize load, and what must be fixed solidly to the base ring? Upper vs. lower plates serve different purposes. • Look at each choice and decide: does that feature more logically secure something to the base ring, or link the shoes to the upper plates so they can tilt and equalize?

✅ Before You Answer

• Clarify in your mind which parts are attached directly to the base ring versus which are attached to or support the thrust shoes. • Make sure you’re focusing on upper leveling plates only; remember that upper and lower plates are held in place differently. • Eliminate any choice that would rigidly lock the upper plates to the base ring if those plates are supposed to float or rock slightly to share the load.
