🔍 Key Concepts

• Focus on how journal bearings in large marine reduction gears are usually constructed. • Look closely at the bearing areas in the cross‑section: do you see any rolling elements (balls or rollers) drawn? • Remember that some bearings are named for the lining material inside the shell rather than their overall shape.

💭 Think About

• Based on the illustration, determine whether this gear set is using a rolling‑element bearing or a plain (sleeve/journal) bearing. • Ask yourself: in heavy marine main reduction gears, which bearing type is most common for carrying high radial loads at relatively low speed? • Consider which choice in the list refers specifically to a soft metal lining poured or bonded into a rigid steel shell.

✅ Before You Answer

• Verify whether the drawing shows balls or tapered rollers; if you don’t see discrete rolling elements, you can likely rule those out. • Check if the bearing appears to be a solid shell with a lining, typical of large engine and reduction gear bearings. • From the remaining answers, pick the one that best matches a plain journal bearing with a soft white‑metal lining used in marine propulsion systems.
