Mobil Centaur XHP™ 221 — Multipurpose Calcium Sulfonate Grease. A high-quality, multipurpose grease designed for rolling bearings in industrial equipment operating at high temperatures and high loads in wet conditions. It offers excellent water and corrosion resistance, mechanical stability, high thermal stability, and load-carrying capability. However, it's important to note that the calcium sulfonate thickener may increase the risk of bearing wear under certain conditions. Recommended for bearings in the wet end of paper machines, high-load industrial ball and roller bearings, and bearings in steel mills and mining operations.
