After adding grease to a ball bearing with a hand-held grease gun, you should __________.

🔍 Key Concepts

• Purpose of the drain plug in a bearing housing during lubrication • How excess grease and pressure affect ball bearings and seals • Why manufacturers specify running the machine briefly after greasing

💭 Think About

• Think about what happens inside the bearing housing if too much grease is trapped with no way out. How does this affect heat and pressure? • Why might it be important to let old grease and any excess new grease leave the bearing area right after greasing? • Which option best protects the bearing seals and prevents overheating, without leaving the housing open to dirt and moisture?

✅ Before You Answer

• Eliminate any options that would leave an opening for dirt or moisture to enter the bearing housing during normal operation. • Be cautious of any option that suggests adding extra grease beyond what’s needed without a way for excess to escape. • Focus on the answer that allows controlled removal of excess grease while the bearing is operating.
