XL-8751
OPEN GEAR AND BEARING GREASE WITH MOLYBDENUM & GRAPHITE
XL-8751 is a calcium sulfonate grease, reinforced with molybdenum and graphite for added
protection. This lubricant is characterized by its exceptional mechanical
stability and resistance to continuous high loads and temperatures.
XL-8751 functions well under very high loads (high EP) rejects water, resists oxidation and
inhibits corrosion.
XL-8751 grease performs extremely well at temperatures within its performance range of -20ºC to
275ºC.
