Selecting the correct grease is one of the most underestimated decisions in maintenance engineering. The wrong choice can lead to premature bearing failure, overheating, contamination, and costly downtime. Understanding the different <\/span>lubricant grease types<\/b> available on the market is therefore essential for technicians, fleet managers, and procurement specialists who want to extend equipment life and reduce operational costs.<\/span><\/p>\n

In this comprehensive guide by <\/span>Merouris<\/b>, we’ll examine the main <\/span>lubricant grease types<\/b>, their composition, the NLGI consistency classification system, and how to match the right grease to your specific application.\u00a0<\/span><\/p>\n

What Is Lubricating Grease and How Does It Work?<\/b><\/h2>\n

Lubricating grease is a <\/span>semi-solid lubricant<\/b> composed of three primary elements: a <\/span>base oil<\/b> (typically 70\u201390%), a <\/span>thickener<\/b> (5\u201320%), and a package of <\/span>performance additives<\/b> (0\u201310%). The thickener acts like a sponge that holds the oil in place, releasing it gradually under load and motion to lubricate moving surfaces.<\/span><\/p>\n

Unlike oils, grease stays in position, seals out contaminants, and provides long-lasting protection in components where re-lubrication is infrequent or impractical. The performance of any grease depends on three key technical parameters:<\/span><\/p>\n
