🔍 Key Concepts

• Heat generation in bearings due to friction and load • Effects of lubrication type and quantity on bearing temperature • How ventilation, alignment, load, and contamination (dirt) each affect bearing operation

💭 Think About

• For each option, ask yourself: would this condition reasonably increase friction or restrict heat removal from a bearing? • Which of the listed items are known general causes of bearing failure or overheating in rotating machinery? • If several options describe real overheating causes, what does that suggest about the combined answer?

✅ Before You Answer

• Verify which factors increase friction in the bearing (misalignment, dirt, lack of proper lubrication). • Check which factors reduce the bearing’s ability to shed heat (poor ventilation, overload). • Confirm that none of the listed conditions would reduce heat as a primary effect; they should all plausibly make the bearing run hotter.
