Future of Engineering

Lubricant cleanliness refers to the absence of contamination. Microscopic particles are the most harmful form of contamination in lubricants. They can irreversibly damage bearing surfaces, shorten the service life of equipment and cause unexpected breakdowns. The concentration of particles in new "as supplied" drums of lubricant can differ by as much as a factor of 1,000, and some bulk lubricants may contain even higher concentrations of particles. This article looks at how microscopic particles contaminate lubricants and damage machinery, and recommends methods to improve lubricant cleanliness.
