WebGreases are classified by penetration number and by type of soap or other thickener. Table 3.7 lists the NLGI grease classification along with a description of the consistency of each class. A penetration number indicates how easily a grease can be fed to lubricated surfaces (i.e. pumpability) or how well it remains in place. WebMost greases produced today use mineral oil as their fluid components. These mineral oil-based greases typically provide …

WebLithium-based greases are the most commonly used; sodium and lithium-based greases have higher melting point (dropping point) than calcium-based greases but are not resistant to the action of water. Lithium-based grease has a dropping point at 190 to 220 °C (350 to 400 °F). However the maximum usable temperature for lithium-based grease is ...
