Typical characteristics

Manufacturer's description

Mobil Vacuoline 146 is the ISO VG 460 grade of the Mobil Vacuoline 100 Series, a range of extra high quality circulating system oils primarily intended for the lubrication of plain bearings in full fluid lubrication systems, particularly those subjected to heavy water contamination, such as back-up roll bearings in metal rolling mills. Its kinematic viscosity is 460 mm²/s at 40 °C and 30.1 mm²/s at 100 °C, with a viscosity index of 95. Formulated from high-quality base stocks and additives, the series delivers outstanding water separation ability, good resistance to thermal degradation and oxidation, and protection against rust and corrosion, while remaining highly resistant to emulsion and sludge formation for cleaner systems and filters. The oil has a high viscosity index and good demulsibility that is retained even under severe water contamination, making it suitable for both single- and dual-tank circulation systems. Mobil Vacuoline 146 has a pour point of -6 °C and a flash point of 296 °C (Cleveland open cup). It is used almost exclusively for rolling mill applications, particularly back-up roll bearing systems, and other full-fluid bearing systems subject to heavy water ingress in related industries. Solid contaminants separate readily, allowing easy cleaning by centrifuge, filtration or settling, which extends oil charge life and reduces maintenance costs. Mobil Vacuoline 146 meets DIN 51517-2:2018-09 and satisfies the Primetals Technologies Morgoil Advanced (Rev 2.5a) and Standard (Rev 1.1) Lubricant Specifications as well as the SMS Group X-Roll Oil Bearing Advanced (SN 180-4) and Standard (SN 180-3) Lubricant Specifications, reflecting strong support from key rolling mill equipment builders.

Applications

• Primarily recommended and used almost exclusively for rolling-mill applications.
• Back-up roll bearings of rolling mills, particularly bearing systems using either a single or dual tank.
• Other full-fluid-film bearing systems and similar applications in other industries, particularly where bearings are subject to heavy water contamination.

Performance & benefits

• Well known and highly regarded worldwide, based on outstanding performance and global technical support, having made it the choice of rolling-mill users around the world.
• Formulated using experience gained in close contact with key rolling-mill builders, including Morgan Construction in the United States, to meet the needs of evolving rolling-mill designs and applications.
• Good resistance to oxidative degradation extends oil charge life and reduces oil-replacement costs.
• Cleaner system and filters, reducing maintenance costs.
• Excellent rust and corrosion protection enhances equipment protection and equipment life.
