Which of the following bearing types would be an example of a plain bearing which substitutes fluid friction for sliding friction?

🔍 Key Concepts

• Plain bearings vs. anti-friction (rolling-element) bearings • How fluid film lubrication works to replace metal-to-metal sliding contact • Typical applications of journal-type bearings in marine machinery

💭 Think About

• Which bearing type relies on a smooth surface with an oil film between the shaft and the bearing, instead of rolling elements? • Look at the names: which options clearly involve rolling elements, and which does not? • On a main engine or propulsion shaft, what kind of bearing usually supports the shaft where it rotates inside a smooth bore with oil lubrication?

✅ Before You Answer

• Identify which choices use rolling elements (balls, rollers, needles) and which is a true plain surface type • Recall that a plain bearing has no separate rolling parts; it relies on a hydrodynamic oil film to carry the load • Confirm that the correct option is commonly used for shaft support in engines with an oil-lubricated running surface
