Mobil Centaur XHP 460 Series

Mobil grease , Senegal

Multipurpose Calcium Sulphonate Complex Grease

Product Description

Mobil Centaur XHP 460 Series greases are a premium family of greases formulated with advanced calcium sulfonate thickener technology. 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 460 Series excels in water saturated environments, providing rust protection between long 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.

 

Mobil Centaur XHP 460 Series greases are particularly well suited to meet the demanding lubrication requirements of steel mill and paper machine equipment.  Mobil Centaur XHP 460 Series greases provide a balanced combination of water washout and water spray-off resistance, as well as excellent corrosion protection, in these severely wet environments. The calcium sulfonate thickeners used are also able to maintain their consistency and EP protection characteristics even with high levels of water contamination.

 

Features and Benefits

Mobil Centaur XHP 460 Series 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, as well as its ability to handle tough applications.  Mobil Centaur XHP 460 Series greases are formulated with high-performance calcium sulfonate thickener technology and are specifically designed for steel and papermill applications.  Mobil Centaur XHP 460 Series greases offer the following benefits:

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

•  Excellent high temperature oil bleed control

•  Reliable bearing lubrication for operations up to 232 C (450 F) with proper re-greasing intervals

•  An advanced polymer additive package which resists water washout

•  Ability to absorb free water, without losing thickener consistency

•  Extended re-grease intervals, reducing grease consumption

 

Applications
