🔍 Key Concepts

• Main bearings function and location on a diesel engine crankshaft • Differences between rolling-element bearings (ball, roller, needle) and plain bearings (bushings with soft lining) • Why large marine propulsion diesels need bearings that can handle heavy, slow-speed, continuous loads and be easily inspected/replaced

💭 Think About

• Think about the size and load characteristics of most propulsion diesel engine crankshafts: which bearing type handles high, steady loads over long periods best? • Which bearing type is easiest to manufacture in halves so it can be installed and removed around a large crankshaft without pressing it off? • Consider which bearing design allows a soft sacrificial layer and hydrodynamic oil film to protect the crankshaft journal.

✅ Before You Answer

• Identify which choices are rolling-element bearings and which are plain sleeve-type bearings • Check which option describes a split design that can be assembled around a crankshaft in place • Confirm which material and construction is typical for precision-machined, hydrodynamically lubricated main bearings in large diesel engines
