Product Description
The Mobil Vacuoline 100 range is a series of extra high quality circulating
system oils primarily intended for the lubrication of plain bearings in
systems designed for full fluid lubrication, particularly those subjected to
heavy water contamination, such as may be used for back-up roll bearings in
metal rolling mills. Specifically, they meet the requirements for Morgoil
rolling mill bearings including the Morgan "super demulsibility" advanced
lubricant specification. The Mobil Vacuoline 100 Series oils are formulated
from high quality base stocks and additives to provide outstanding water
separation ability, good resistance to thermal degradation and oxidation, and
protection against rust and corrosion.
The Mobil Vacuoline
100 Series oils are resistant to the formation of emulsion and sludge.
Consequently the oils can contribute to cleaner systems and filters. Also
solid contaminants separate readily for easy cleaning by centrifuge,
filtration or settling. The Mobil Vacuoline 100 Series possess a high
viscosity index and good demulsibility that is retained under conditions of
severe water contamination and are recommended for both single and dual tank
circulation systems.
Mobil Vacuoline 100 Series oils are the
choice of rolling mill operators worldwide. They enjoy strong support of key
equipment builders including Morgan Construction Company, Worcester, MA, USA.
Features and Benefits
The Mobil Vacuoline family of products is well known and highly regarded
worldwide based on their outstanding performance and the global technical
support which stand behind the brand. The exceptional performance of Mobil
Vacuoline 100 Series oils, has made it the choice of rolling mill users around
the world. Experience gained in close contact with key rolling mill builders,
including Morgan Construction in the United States has been applied to ensure
that Vacuoline oils meet the needs of evolving rolling mill designs and
applications.
For Mobil Vacuoline 100 Series oils, this work
has resulted in a formulation based on a high quality base stocks, along with
specially chosen additives, to provide rust and corrosion protection and
excellent demulsibility which results in superb equipment protection, highly
reliable operation and long oil charge life. A review of the features,
advantages and potential benefits of the product are shown below:
