What type of oil problem can lead to bearing issues?

Improper viscosity of oil can lead to significant bearing issues because viscosity refers to the thickness or resistance to flow of the lubricant. If the viscosity is not appropriate for the specific operational conditions of the equipment, it can result in inadequate lubrication. For example, if the viscosity is too low, the oil may not provide enough film strength to protect the bearings from metal-to-metal contact. Conversely, if the viscosity is too high, it may hinder the oil from circulating effectively, leading to insufficient lubrication and increased friction, ultimately resulting in overheating and wear.

Additionally, the correct viscosity ensures that the oil can fill the spaces between moving parts effectively and maintain a consistent lubricating film under a range of operating conditions. This is vital for the efficient and safe operation of bearings, as they rely on a proper layer of oil to function optimally, reduce wear, and prolong their lifespan.
