At what temperature should the journal bearing be closely monitored to avoid overheating?

• A. 200°F
• B. 220°F
• C. 240°F
• D. 250°F

Answer: (D)

Monitoring the temperature of a journal bearing is crucial to ensure its efficient operation and to prevent overheating, which can lead to failure. The correct answer indicates that at a temperature of 250°F, significant attention should be given to the journal bearing. At this temperature, it's likely that the lubricant properties may start to degrade, leading to increased friction and wear. Excessive heat can compromise the integrity of the bearing materials themselves, resulting in potential damage or catastrophic failure if not addressed promptly. While the other temperatures listed may also be important to monitor, 250°F is generally recognized in many mechanical systems as a critical threshold where overheating becomes a serious risk, and appropriate maintenance actions should be initiated. It's essential to be vigilant at this temperature to ensure safe and effective operation of machinery. Overall, consistent monitoring around this temperature can help prevent long-term damage and maintain operational safety.
