Mobil Centaur XHP 461 (55 Gal. Drum)

Mobil 103918

High-quality Mobil Centaur XHP 461 grease is created using advanced calcium sulfonate thickener technology, specifically formulated for steel and paper mill applications. In contrast to soap-based thickeners, the calcium sulfonate thickener excels in water-saturated and Extreme Pressure (EP) environments, protecting against rust and corrosion without requiring frequent relubrication. Rated NLGI Grade 1, Mobil Centaur XHP 461 is exceptionally reliable and consistent under EP conditions, and has superior high-temperature oil bleed control. Its formulation is ideal for the severe challenges of steel mill and paper machine equipment, providing a balance of resistance to water washout and water spray-off, while also inhibiting corrosion in these extremely wet environments. Mobil Centaur XHP 461 can absorb free water without losing thickener consistency, and is a top choice for heavily loaded and water-saturated applications such as ladle turret bearings, continuous casters, hot rolling work, roll bearings and roll necks.
