When your heavy-duty industrial bearings are moving slow but carrying massive tonnage, standard grease gets squeezed out. Mammoth utilizes the 460 because its higher viscosity base oil creates a "cushion" that won't fail under pressure.

Phillips 66® Omniguard 460 is a high-performance, heavy-duty, extreme-pressure calcium sulfonate grease specially developed for use in industrial equipment operating under heavy loads in wet or corrosive environments. It is characterized by its high-viscosity base oil (ISO 460) which provides a superior lubricating film for slow-speed, heavily loaded bearings. It offers excellent resistance to water washout, superior rust and corrosion protection, and high dropping point for performance in extreme heat.
