Mobil Centaur XHP 462
Mobil Centaur XHP 462 is a premium multipurpose grease formulated using advanced calcium sulphonate complex thickener technology to provide outstanding lubrication performance in demanding industrial applications. Designed for use in heavily loaded and water-saturated environments, Mobil Centaur XHP 462 delivers excellent protection against corrosion, strong load-carrying capability and long service life. The grease is particularly suited for use in industries such as steel mills and paper manufacturing where equipment operates under harsh and wet conditions.
One of the key advantages of Mobil Centaur XHP 462 is its exceptional resistance to water washout and spray-off. The calcium sulphonate thickener system enables the grease to maintain its consistency and lubrication performance even when exposed to high levels of water contamination. This ensures reliable protection of bearings and components operating in wet environments, reducing downtime and improving operational efficiency.
Mobil Centaur XHP 462 also provides outstanding extreme pressure (EP) performance and load-carrying capability. The inherent EP properties of the thickener system allow the grease to perform effectively under heavy and shock loading conditions, helping protect critical components such as bearings, roll necks and casting equipment. This makes it ideal for demanding industrial applications where equipment is subject to high loads and challenging operating conditions.
Another important benefit of Mobil Centaur XHP 462 is its excellent corrosion protection. The formulation helps prevent rust formation even in environments where moisture exposure is frequent. In addition, the grease has the ability to absorb free water without losing its structural integrity, ensuring continued lubrication performance and protection in severe wet conditions.
Mobil Centaur XHP 462 also delivers excellent thermal stability and oxidation resistance. The grease maintains its structure and performance at elevated temperatures, supporting reliable lubrication for applications operating up to approximately 232°C with appropriate re-greasing intervals. Its controlled oil bleed characteristics help maintain consistent lubrication while reducing the risk of oil separation during high-temperature operation.
Mobil Centaur XHP 462 is recommended for heavily loaded industrial applications operating in water-saturated environments, particularly in steel and paper mill operations. Typical applications include ladle turret bearings, continuous casters, hot rolling work roll bearings, roll necks and paper machine components such as couch, press and breast rolls. The grease meets DIN 51825 KPF 1 K -20 performance requirements, confirming its suitability for demanding industrial lubrication conditions.
Physical characteristics include an NLGI grade of approximately 2, with a base oil viscosity of approximately 460 mm²/s at 40°C and 30.8 mm²/s at 100°C. Mobil Centaur XHP 462 has a viscosity index of around 96, a dropping point of approximately 275°C and a weld load of approximately 400 kgf. The grease also demonstrates excellent resistance to water washout of approximately 0.5% at 79°C and water spray-off of approximately 20%, supporting reliable lubrication performance in severe wet and heavily loaded industrial environments.
