🔍 Key Concepts

• Kingsbury thrust bearing design and purpose • How tilting pads / shoes support and transmit thrust from the shaft • The role of the thrust collar relative to the shaft (does it rotate or stay fixed?)

💭 Think About

• Think about which parts must move with the shaft to transmit axial thrust into the bearing and which parts stay in the housing. • Consider how an oil film is formed between the shoes and the collar—what kind of shoe mounting helps maintain a stable wedge of oil? • Look carefully at the options that talk about lubrication type versus the actual mechanical construction of the bearing.

✅ Before You Answer

• Verify which component in a Kingsbury bearing actually rotates with the shaft (collar or shoes?). • Check whether Kingsbury bearings are specifically defined by pivoted tilting shoes rather than a particular surface coating or oiling device. • Eliminate any choice that only describes a general lubrication feature and not the distinctive Kingsbury construction.
