Question 1 of 27070

In most pumps and pump motors, over packing the ball bearings full of grease will result in __________.

🔍 Key Concepts

• lubrication of rolling-element (ball) bearings in pump motors • effect of too much grease vs. too little grease on bearing temperature and life • how grease actually circulates and moves inside a bearing during operation

💭 Think About

• What happens to the balls in a bearing if there is so much grease that they cannot freely roll and push grease out of the way? • Does an over-packed bearing usually run cooler or hotter, and why would that be? • Which choices describe a normal, healthy flow of grease, and which describe a restricted or abnormal condition?

✅ Before You Answer

• Identify which options describe a negative consequence that commonly occurs when a bearing cavity is overfilled with grease. • Eliminate any option that sounds like a description of ideal lubrication and cooling. • Think about whether over-packing would make it easier or harder for grease to circulate and carry away heat from the bearing.

In most pumps and pump motors, over packing the ball bearings full of grease will result in __________.

moisture emulsification of the bearing grease

insufficient circulation and overheating of the bearing

proper grease circulation to cool the bearing
