XL8751

OPEN GEAR AND BEARING GREASE WITH MOLYBDENUM & GRAPHITE

XL8751 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.

XL8751 functions well under very high loads (high EP) rejects water, resists oxidation and inhibits corrosion.

XL8751 grease performs extremely well at temperatures within its performance range of -20ºC to 275ºC.

TYPICAL APPLICATIONS:  
• Industrial equipment in an adverse environment or under
heavy loads
• Gears operating at low or high
speeds
• Open gears exposed to water• Cables, wire ropes
• Heavily loaded bearings• Crusher bearings
• Low RPM bearings • Roller bearings
• Pins & Bushings• High temperature ball bearings
• Heavy machinery• Rotary joints
• Truck fifth wheel
