🔍 Key Concepts

• How ball bearings are lubricated and what grease is supposed to do inside a bearing • What happens to friction and heat if rolling elements have to push through excess grease • How over-packing a confined space (like a bearing housing) can affect temperature and wear

💭 Think About

• Think about whether grease is mainly there to FILL all available space or to provide a THIN FILM between moving parts • Consider what happens to moving parts when they must churn through a thick mass of grease at high speed • Ask yourself: which options describe a negative consequence that a maintenance question is likely to warn you about?

✅ Before You Answer

• Identify which options sound like obviously positive outcomes (these are less likely to be the result of a maintenance error like over greasing) • Focus on the choice that involves heat and friction inside the bearing • Mentally picture a bearing cavity: if it is overfilled, what happens to the temperature when the shaft is turning at speed?
