Premium Calcium Sulfonate Grease with Molybdenum Disulfide

Product Description

Mobil Centaur™ XHP 150 Mine Series greases are a premium family of greases formulated with advanced calcium sulfonate thickener technology and 5% molybdenum disulfide. The series is specifically designed for the lubrication of extra heavy-duty off-highway and mining equipment. The calcium sulfonate thickener carries both inherent rust protection and extreme pressure (EP) properties. Compared to conventional soap-base thickeners (i.e. lithium, aluminum, calcium soaps), the calcium sulfonate thickener used in Mobil Centaur XHP 150 Mine Series excels in water saturated environments, providing longer re-lubrication intervals. The inherent EP properties exhibit great stability in the presence of water, allowing a balance between wear protection and resistance to corrosion.

Features and Benefits

Mobil Centaur XHP 150 Mine, 151 Mine and 152 Mine were specifically designed to meet the needs of off-highway and mining equipment that required exceptional EP performance and which would remain in place even in tough conditions of water spray, high sliding, and high temperatures.

These greases offer the following features, advantages, and potential benefits:

• Excellent extreme-pressure protection and load-carrying ability for equipment protection under heavy and shock loading

• Excellent high temperature oil bleed control

• An advanced polymer additive package which resists water washout

• Ability to absorb free water, without losing thickener consistency

Applications

Mobil Centaur XHP Mine Series greases are recommended for severe off-highway and mining applications in terms of operational severity and

saturated water environments.

Specific applications include:

• Bucket pins, pivot pins, and heavily loaded chassis components

• Heavy equipment central lubrication systems (Mobil Centaur XHP 150 Mine and Mobil Centaur XHP 151 Mine)

• General purpose chassis lubrication
