🔍 Key Concepts

• Difference between rolling-element bearings and plain/sleeve/journal bearings • How friction is reduced: fluid-film (hydrodynamic) friction vs rolling contact friction • Typical examples of ball, roller, and journal bearings in machinery

💭 Think About

• First, separate which bearings rely on a smooth surface with a film of lubricant and which rely on rolling elements like balls or rollers. • Ask yourself: which option clearly has balls or rollers that roll between two races, instead of just a shaft turning in a lubricated bore? • Think about which bearings are usually used for crankshafts and propeller shafts and whether those are rolling-element or plain-type bearings.

✅ Before You Answer

• Identify which choices are plain (fluid-film) bearings that primarily use fluid friction instead of rolling elements. • Identify which choice clearly contains discrete rolling elements (like balls) between inner and outer races. • Before selecting, double-check that the bearing you choose truly substitutes sliding contact with rolling contact, not just adds more lubrication.
