🔍 Key Concepts

• Materials commonly used for water-lubricated stern tube bearings on large ships • Properties needed: low friction, good lubrication with seawater, and resistance to swelling/rot • Difference between a bearing lining material and a metal housing or bushing

💭 Think About

• Look at each option and ask: which of these is traditionally known as a lining material for water-lubricated stern tube bearings? • Which material would run well directly against a steel shaft while being cooled and lubricated by seawater? • Is there any option that sounds more like a support or housing material rather than the actual bearing surface in contact with the shaft?

✅ Before You Answer

• Verify which materials (wood, rubber, resin) are historically used in stern tube bearing linings on large vessels • Consider whether metal-to-metal contact (steel shaft on metal bearing) is desirable in a stern tube with seawater lubrication • Distinguish between a soft bearing surface and a metal shell/bushing that simply holds the bearing material
