Mobilgrease XHP™ 460 Series
Mobilgrease XHP™ 460 Series lithium-complex greases are designed for a wide range of heavy-duty applications including the industrial, automotive, construction and marine sectors. These Mobil™ greases exhibit excellent adhesion and cohesion properties and mechanical stability. They are formulated to excel in extreme conditions, such as:
- High operating temperatures
- Contaminated environments (water, dust, dirt)
- Heavy loading
- Extended relubrication intervals
Features and Benefits
A key factor in the excellent adhesion and cohesion properties and mechanical stability of the thickener of Mobilgrease XHP 460 greases is the proprietary manufacturing technology developed at our research facilities and adopted by our modern manufacturing facilities. These products use specially selected additives to provide excellent oxidation stability, rust and corrosion control, resistance to water contamination as well as anti-wear and EP protection. Mobilgrease XHP 460 Series products offer the following features and potential benefits:
Mobilgrease XHP 460 greases are leading members of the Mobilgrease brand of products. Mobilgrease XHP 460 greases are designed by our formulation technologists and backed by our world-wide technical support staff.
Features
Advantages and Potential Benefits
Superb resistance to water washout and spray-off
Helps to assure proper lubrication and protection even in the most severe water exposure conditions
Highly adhesive and cohesive structure
Excellent grease tenacity helps reduce leakage and extend re-lubrication intervals to help reduce maintenance requirements.
Excellent rust and corrosion resistance
Protection of lubricated parts even in hostile aqueous environments.
Very good resistance to thermal, oxidative and structural degradation at high temperature
Helps extend grease life and enhance bearing protection in high temperature applications and offers reduced maintenance and replacement cost benefits.
Very good anti-wear and EP performance
Reliable protection of lubricated equipment, even under conditions of high sliding with potential for extended equipment life and reduced unanticipated downtime
Broad multi-purpose application
Provides potential for inventory rationalization and reduced inventory costs
Applications
Mobilgrease XHP 460 greases are used in a wide range of equipment including industrial, automotive, construction and marine applications. The blue color of Mobilgrease XHP 461 and 462 enables easy verification of application. With its high, ISO VG 460 base oil viscosity, these greases are recommended for high load applications at slow-to-moderate speeds, including most bearing applications in the paper, construction, and mining industries, as well as off-highway vehicles.
Specific applications:
• Mobilgrease XHP 461 is recommended by ExxonMobil for use in industrial and marine applications, chassis components and farm equipment. It provides excellent low temperature performance. It is satisfactory for low speed flexible gear-type couplings.
• Mobilgrease XHP 462 Series is recommended for use in felt roll bearings, wet end bearings, and press section bearings. It is also a good multi-purpose grease for general mill applications and industrial and marine applications, chassis components and farm equipment.
• Mobilgrease XHP 462 Moly is fortified with 3% molybdenum disulfide and is particularly recommended by ExxonMobil for applications such as bucket pins and fifth wheels, where molybdenum disulphide provides an extra level of protection where sliding friction and oscillating motion can lead to rupturing of the oil film, resulting in metal to metal contact.
