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.

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
