NLGI (National Lubricating Grease Institute) grades define grease consistency, ranging from #000 (softest) to #6 (hardest). For high-speed bearings, a softer NLGI #1 or #2 lithium grease reduces friction, while heavy-duty machinery like mining equipment needs harder #3 grades for load resistance. Understanding NLGI ratings ensures optimal performance—soft greases for fluidity, hard ones for structural stability—tailoring lubrication to your application’s demands.

We offer greases under different NLGI grades, welcome contact us for more information.
