Antifriction bearings should not be excessively lubricated because __________.

🔍 Key Concepts

• purpose of lubrication in antifriction (rolling element) bearings • what happens to friction and heat when there is too much grease or oil in a confined space • how rolling elements move when the space is overfilled with lubricant

💭 Think About

• Think about how a rolling-element bearing (balls or rollers) normally reduces friction. What path do those elements need to follow, and how could extra lubricant interfere with that? • Consider what happens to temperature and pressure inside the bearing housing if you pump in too much grease. Does that make the bearing cooler or hotter? • Which of the choices describes a realistic, common failure effect that maintenance personnel are warned about when they over-grease a bearing?

✅ Before You Answer

• Verify which option is most directly related to heat buildup and energy loss caused by internal churning of excess grease or oil • Eliminate any answers that describe conditions that are not a typical or primary result of over-lubrication in rolling bearings • Check which choice best matches what happens when rolling elements must plow through excess lubricant instead of rolling freely on a thin film
