What is one of the most critical contaminants of lubrication?

Water is considered one of the most critical contaminants in lubrication due to its detrimental effects on lubricants and machinery. When present, water can lead to several issues, including corrosion of metal surfaces, which compromises the integrity of components. It can also decrease the lubricating properties of the oil, leading to inadequate lubrication and increased wear on mechanical parts. Additionally, water can promote the formation of sludge and other deposits that can hinder the performance of the lubrication system.

While dust, air, and debris can also be contaminants that affect lubrication, water stands out because of its ability to cause severe damage not only to the lubricant itself but also to the equipment it is meant to protect. Moreover, water can enter the lubrication system through various means, such as condensation, leaks, or contamination during storage or handling, making its management especially crucial for maintaining reliable machinery operation and prolonging equipment life.
