What does oil migration refer to in lubrication?

Oil migration refers to the displacement of lubricant from its intended locations within machinery. In the context of lubrication, it is a critical concept because effective lubrication relies on keeping the oil in the correct areas to ensure proper coverage and protection of machine components. When oil migrates, it can lead to insufficient lubrication, potentially resulting in increased wear and tear, overheating, and even failure of the equipment.

This phenomenon can be caused by various factors such as high temperatures, centrifugal force, or the movement of parts within the machinery. Understanding oil migration helps technicians implement better lubrication practices and ensure that lubricants are effectively serving their purpose, thus enhancing the longevity and efficiency of machinery.
