🔍 Key Concepts

• Kingsbury thrust bearing construction and purpose • How axial thrust is carried from a rotating shaft into a hydrodynamic oil film • The different roles of collar, shoes (pads), leveling plates, and base ring in the assembly

💭 Think About

• Visualize the path of the thrust load: it starts at the line shaft and must end up as a pressure in the oil film under the shoes. Which part physically touches the shaft and passes this force into the shoes? • Think about which components are stationary and which rotate with the shaft. The rotating member that faces the shoes will be the one that delivers the thrust to the oil film. • Ask yourself: which parts are mainly for support and alignment (load distribution) versus which part is the primary contact surface taking the shaft’s thrust?

✅ Before You Answer

• Identify which component is attached to or integral with the shaft and rotates with it. • Confirm which components are stationary support members (do not rotate) that only distribute load among shoes. • Make sure the component you choose is the one that directly converts shaft axial force into pressure on the oil film between it and the shoes, not just a structural base or leveling device.
