Mobil Vacuoline 128
Mobil Vacuoline 128 is part of the Mobil Vacuoline 100 Series, a range of extra high-quality circulating system oils primarily intended for lubrication of plain bearings operating under full fluid film conditions. These oils are particularly suited to rolling mill applications where heavy water contamination may occur, such as back-up roll bearings. The formulation provides excellent water separation, oxidation resistance and protection against rust and corrosion for reliable operation.
One of the key advantages of Mobil Vacuoline 128 is its outstanding demulsibility. The oil separates readily from water and contaminants, helping maintain lubrication performance even under severe water contamination. This contributes to cleaner systems, improved filtration efficiency and reduced downtime.
Mobil Vacuoline 128 also provides strong resistance to oxidation and thermal degradation. The formulation helps extend oil service life and reduce sludge formation. This supports cleaner systems, longer filter life and reduced maintenance costs. The oil also offers excellent rust and corrosion protection for system components.
Another important benefit is its suitability for circulating bearing systems. Mobil Vacuoline 128 is recommended for back-up roll bearings in rolling mills and other full fluid bearing systems. The oil performs well in both single and dual tank circulation systems and helps solid contaminants separate easily for removal by centrifuge or filtration.
Mobil Vacuoline 128 meets rolling mill lubricant requirements including Primetals Technologies Morgoil specifications and SMS Group X-Roll bearing specifications. The ISO VG 150 viscosity provides dependable film strength and reliable lubrication in heavily loaded bearing systems.
Physical characteristics include ISO VG 150 viscosity grade with a kinematic viscosity of approximately 150 mm²/s at 40°C and 14.8 mm²/s at 100°C. Mobil Vacuoline 128 has a flash point of approximately 280°C and a pour point of approximately −9°C. The oil provides reliable water separation, corrosion protection and long service life in circulating system applications.
