🔍 Key Concepts

• Identify where the shaft actually rides inside the bearing – this is the true bearing surface. • Distinguish between the bearing shell/pads and the surrounding housing or cover which only supports the bearing. • Look for the curved, concentric surfaces around the shaft that are likely lined with bearing material (e.g., babbitt).

💭 Think About

• On MO-0120, which numbered parts are in direct sliding contact with the shaft when it rotates? • Which numbers point to the inner curved faces that would form the oil film around the shaft, rather than the outer support or cover? • Compare top and bottom views: which two numbers together form a complete 360° support around the journal when assembled?

✅ Before You Answer

• Confirm that the items you pick are the inner surfaces, not just the blocks or housings that hold them. • Make sure both chosen numbers lie on components that are concentric with the shaft centerline. • Verify that the two items together could reasonably form the load‑carrying journal surface (upper and lower halves or pads) of this bearing.
