Bearings, seals and lubrication — the parts that actually fail
How a hydrodynamic journal bearing carries load on a film of oil, why babbitt is deliberately soft, what a mechanical seal is really sealing, why the seal chamber environment decides seal life, and what an API 682 flush plan is doing.
Vibration and alignment — reading a spectrum and getting the shaft straight
Why 1X usually means unbalance and 2X usually means misalignment, what a proximity probe sees that a casing accelerometer cannot, why hot alignment differs from cold, what resonance does to an otherwise healthy machine, and why a coast-down tells you something a steady run never will.
