Premium Calcium Sulfonate Grease with Molybdenum Disulfide

Product Description

Mobil Centaur™ XHP 151 Mine grease is a premium grease formulated with advanced calcium sulfonate thickener technology and 5% molybdenum disulfide. This grease 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 151 Mine 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 151 Mine was 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.

This grease offers 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 151 Mine grease is 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

• General purpose chassis lubrication
