Lubricant Contaminants Limit Gear Life | Gear Solutions .

Lubricant cleanliness refers to the absence of contamination. 1 Microscopic particles are the most harmful form of contamination in lubricants. They can irreversibly damage gear and bearing surfaces, shorten the service life of equipment, and cause unexpected breakdowns. 1-4 The concentration of particles in new “as supplied” drums of lubricant can differ by as much as a factor of 1,000 ...
