Mobilgrease XHP 461 is the NLGI 1 grade of the Mobilgrease XHP 460 series of extended-service, heavy-duty lithium complex greases, formulated with an ISO VG 460 base oil (460 mm²/s at 40°C). It offers excellent high-temperature performance, adhesion, structural stability, resistance to water contamination and strong rust and corrosion protection, with a dropping point of 270°C and a maximum recommended operating temperature of 140°C. With its high base-oil viscosity, it is recommended for high-load applications at slow-to-moderate speeds, including bearings in the paper, construction and mining industries and off-highway vehicles. ExxonMobil recommends it for industrial and marine applications, chassis components and farm equipment; it offers excellent low-temperature performance and is satisfactory for low-speed flexible gear-type couplings. It meets the requirements of DIN 51825 KP 1 N -20 L and offers superb resistance to water washout and spray-off, along with very good anti-wear and extreme-pressure performance (four-ball weld point 315 kgf), helping extend equipment life and reduce unplanned downtime.
