Mobil Vacuoline 133 is an extra high quality circulating system oil that is primarily intended for the lubrication of plain bearings in systems designed for full fluid lubrication, particularly those subjected to heavy water contamination. It is specifically formulated to meet the requirements for rolling mill bearings, including the Morgan "super demulsibility" advanced lubricant specification. Mobil Vacuoline 133 is made from high quality base stocks and additives that provide outstanding water separation ability, good resistance to thermal degradation and oxidation, and protection against rust and corrosion. It is also resistant to the formation of emulsion and sludge, which helps to keep systems and filters cleaner. Solid contaminants can also be easily removed by centrifuge, filtration or settling. Mobil Vacuoline 133 has a high viscosity index and good demulsibility that is retained under conditions of severe water contamination. It is recommended for both single and dual tank
