🔍 Key Concepts

• In a pivoted shoe thrust bearing, the base ring is the stationary part that supports the shoes and fits into the bearing housing • Look at how the parts are arranged in the exploded view: top elements usually relate to the rotating collar, while the lower elements are fixed/support parts • Each letter points to a specific component – compare which one clearly serves as the large support ring for the shoes rather than an individual shoe or retainer

💭 Think About

• Which lettered part appears to be the main stationary support for the bearing shoes when the assembly is put back together? • When re‑assembled, which part would logically be in contact with the bearing housing, not directly with the rotating shaft collar? • Which parts are obviously individual shoes or retainers, and which one looks like the solid ring that they would sit on?

✅ Before You Answer

• Be sure you can distinguish between individual shoes and the support ring they rest on • Verify which component is likely the rotating collar/runner attached to the shaft; the base ring will be the other large ring that stays fixed • Confirm that the choice you pick is the part that would be at the bottom of the stack in the housing, carrying the shoes rather than being carried by them
