Mobil Almo 500 Series lubricants are premium quality high performance products primarily intended for the lubrication of pneumatically operated rock drills in underground and surface mining operations. The Mobil Almo Series oils are formulated from high quality base stocks and additives, which provide excellent chemical stability and good protection against wear and corrosion. They offer an optimum balance of adhesiveness, yet are emulsifiable enough to pick up moisture carried in the air stream reducing the negative effects of water on wear and corrosion. They do not form gummy deposits that could cause sluggish valve action. Even in the presence of water, the Mobil Almo 500 Series oils have good preferential metal-wetting properties that maintain continuous oil films. These properties in combination with high EP characteristics help provide excellent lubrication resulting in long equipment life.
Mobil Almo 500 Series possess high viscosity indexes and low pour points to ensure good lubrication at the low temperatures resulting from air expansion and guard against icing stoppages while providing adequate films on drill parts that may operate at high temperatures. Oil fog generation levels are extremely low.
The Mobil Almo 500 Series oils provide an optimum performance balance which assures long equipment life and minimal maintenance costs. Their excellent wear protection characteristics and ability to provide adequate lubrication in the presence of water not only reduces wear but protects against rust and corrosion. Their good chemical stability prevents sludge and deposit formation reducing the need for frequent maintenance.
| Features | Advantages and Potential Benefits |
|---|---|
| Effective Chemical Stability | Reduce sludge and deposit formation Improves valve operation |
| Desired Emulsifiable Properties | Effective lubrication in presence of water |
| High Viscosity Index | Provides good lubrication at both high and low temperatures |
| Excellent Load Carrying Ability and Anti-Wear Protection | Reduces component wear Prolongs equipment life Reduces maintenance costs |
| Very Good Adhesive Characteristics | Protects metal surfaces from corrosion Provides good lubricant films under all conditions |
| Rust and Corrosion | Longer tool life Increased tool performance |
Mobil Almo 500 Series oils are recommended for use in all pneumatically operated rock drills in both underground and surface mining as well as in contractor and other industrial applications. They are suitable for percussive- and rotary- type tools. The viscosity grades allow selection for year-round use where seasonal ambient temperature variations are extreme.

The Mobil Centaur? Moly Series of greases are premium quality greases formulated with advanced calcium sulfonate thickener technology. The calcium sulfonate thickener in the Mobil Centaur Moly products represents a significant advance in grease formulation technology. Unlike conventional soap-base thickeners (i.e. lithium, aluminum, and calcium soaps), the calcium sulfonate thickener does much more than simply impart consistency. It imparts excellent corrosion and water-resistance properties to the grease and has inherent extreme-pressure protection properties that enhance load-carrying ability. Further, the EP properties derived from the calcium thickener also have inherently better thermal stability than those from conventional Sulphur/Phosphorus EP additives.
Fortified with 3% molybdenum disulphide to complement a robust extreme-pressure additive system, the Mobil Centaur Moly Series of greases are particularly well suited to meet the demanding lubrication requirements of heavy-duty truck chassis, construction and mining equipment, and heavily load industrial bearings. The Mobil Centaur Moly Series also provides outstanding resistance against the effects of water washout, water spray-off and corrosion, and are available in NLGI 1 and 2 grades offering a range of pumpability and dispensing options.
The Mobil Centaur Moly greases are members of the Mobil? brand of lubricating products recognized for their high quality and reliability, as well as performance capabilities. This family of products is manufactured to the strictest quality standards. A key feature for this product family is its reputation for reliability and consistency, and its ability to handle tough applications. The Mobil Centaur Moly Series are formulated with state-of-the-art high-performance calcium sulfonate thickener technology and is formulated for heavy-duty truck, mining and construction applications as well as heavily loaded industrial bearings. The Mobil Centaur Moly greases offer the following potential benefits:
Excellent extreme-pressure protection and load-carrying ability for equipment protection under heavy and shock loading
Fortified with 3% molybdenum disulphide for retention of EP performance and equipment protection in severe sliding situations
Outstanding corrosion and water resistance for highly reliable lubrication in hostile environments
The Mobil Centaur Moly Series of greases are highly recommended for heavily loaded applications or environments highly contaminated with water. Specific examples of such applications include:
Heavy-duty trucks, including chassis, spring shackles, king pins, tie rods, u-joints, hinge and bucket pins and fifth wheels
Mining and construction equipment
Marine equipment
Highly loaded industrial bearings
