Description
Castrol Molub-Alloy® 6780 is a wide temperature bearing grease designed for year-round service in both
bushings and antifriction bearings. Castrol Molub-Alloy 6780 matches the tough service requirements of
mining applications, including bearings and bushings of excavating equipment subjected to broad service
temperature ranges as well as off-road mobile equipment general lubrication.
Castrol Molub-Alloy 6780 was developed with emphasis on the following performance characteristics:
Broad service temperature application range for year-round service.
Low temperature pumpability
Work-shear stability to be effective in severe mining and off-road mobile equipment applications.
Resistance to the washing action of water.
Molub-Alloy 6780 contains a proprietary blend of solid lubricants that includes 5% molybdenum disulfide
(<10 micron) together with extreme pressure (EP) chemical additives which work synergistically to
provide the high degree of anti-wear and EP characteristics required in heavy duty off-road service.
To provide corrosion protection in wet seasons and protection from aging in long service at high
temperatures, Molub-Alloy 6780 is further fortified with effective rust and oxidation inhibitors.
Applications
Molub-Alloy 6780 may be used for bushings and bearings of draglines, shovels, drills, mobile equipment,
and various mill applications. It is certified to Bucyrus International SD 4711 multi-purpose bearing grease
specification.
Molub-Alloy 6780 is recommended for use in an ambient temperature operating range of -40°F (-40°C) to
150°F (60°C).
Advantages
Exceptional water resistance – coating film stays on the surface even in presence of water
Excellent EP and anti-wear properties – easier startup and protects equipment against
extreme/shock loading and helps minimize bearing component wear and hence extends
equipment life
Excellent mechanical stability and adhesion – grease keeps its consistency in service ensuring
long term protection and reduced consumption as film stays between lubricated surfaces
Outstanding oxidation/thermal stability – provides reliable performance and extended lubricant life
Excellent pumpability– remains pumpable down to -40°F(-40°C)
Formulated to address environmental concerns - it is free of antimony, barium, lead, and zinc.
