For troubleshooting a hot running bearing, which of these is an acceptable course of action?

Relieving pressure from the bearing is a valid course of action when troubleshooting a hot running bearing. This approach can help reduce friction and heat generation within the bearing system. By alleviating excess pressure, you allow for improved lubrication flow, which can enhance cooling and efficiency.

Finding the root cause of the overheating is critical, and relieving pressure may mitigate the immediate issues while a detailed inspection and corrective actions are performed. It’s important to understand that excessive pressure can lead to increased heat generation due to higher friction, so managing this pressure is key to resolving the issue effectively.

The other options, while they may seem relevant, do not directly address the immediate concern of a hot running bearing as effectively. Increasing lubrication frequency might help, but if there is an underlying issue causing excessive heat or friction, it may not provide enough relief. Reducing operating temperature settings is more of a preventative measure than a direct solution to a hot bearing. Removing the bearing entirely would lead to operational failure and is not a practical step for troubleshooting a hot-running issue.
