What is the primary indication of a grease lubricated bearing that is over-lubricated in terms of the quantity of grease in the housing?

🔍 Key Concepts

• Effect of excess grease on bearing operation • Relationship between lubrication quantity and bearing temperature • How over-lubrication affects friction, churning, and noise/vibration

💭 Think About

• If a bearing housing is packed with too much grease, what happens to the rolling elements as they try to move through it? Does this increase or decrease friction and heat? • Compare which symptom would be most directly and consistently affected by extra churning of grease: sound, temperature, or vibration? • Think about normal vs. over-lubricated conditions: which way would the operating temperature logically shift when the bearing has to work harder to push through thick grease?

✅ Before You Answer

• Identify which option directly reflects a change in temperature rather than sound or vibration alone. • Decide whether extra resistance from excess grease would tend to make the bearing run hotter or cooler. • Eliminate any choice that does not clearly connect to the effect of increased churning friction in the grease.
