🔍 Key Concepts

• Heat generation in bearings due to friction and churning of lubricant • Effect of grease quantity and consistency on temperature and friction • Difference between proper lubrication vs. over-lubrication in anti-friction bearings

💭 Think About

• How does the amount of grease inside a bearing affect how much it is churned and heated as the bearing rotates? • What happens to bearing cooling and protection if the grease is too thick or too thin? • Which option best describes a condition that minimizes internal friction and churning while still providing a lubricating film?

✅ Before You Answer

• Check which option reduces churning of grease inside the bearing at operating speed • Eliminate any option that would likely increase friction or drag in the bearing • Consider which choice is most consistent with manufacturer recommendations for filling anti-friction (ball/roller) bearings with grease
