Mobil Vacuoline 146
Mobil Vacuoline 146 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 demulsibility, oxidation resistance and rust protection for dependable operation.
One of the key advantages of Mobil Vacuoline 146 is its outstanding water separation capability. The oil separates readily from water and contaminants, helping maintain lubrication performance even under severe water contamination. This supports cleaner systems, improved filtration efficiency and reduced downtime.
Mobil Vacuoline 146 also provides strong resistance to oxidation and thermal degradation. The formulation helps extend oil charge life and reduce sludge formation. This contributes to 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 146 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 allows solid contaminants to separate easily for removal by centrifuge, filtration or settling.
Mobil Vacuoline 146 meets rolling mill lubricant requirements including Primetals Technologies Morgoil specifications and SMS Group X-Roll oil bearing specifications. The ISO VG 460 viscosity provides strong film strength and dependable lubrication in heavily loaded bearing systems.
Physical characteristics include ISO VG 460 viscosity grade with a kinematic viscosity of approximately 460 mm²/s at 40°C and 30.1 mm²/s at 100°C. Mobil Vacuoline 146 has a flash point of approximately 296°C and a pour point of approximately −6°C. The oil provides reliable water separation, corrosion protection and long service life in circulating system applications.
