Addressing Overheating in Journal Bearings

We’ve been dealing with overheating in journal bearings, especially during startups. What’s your approach to diagnosing and resolving this issue?

Inspect the oil cooling system. Blocked or inefficient coolers are a common cause of overheating.

Check for excessive preload on the bearings. Incorrect installation often causes higher friction and heat.

Install vibration sensors. High vibration often correlates with overheating in journal bearings.
