Mobil Vacuoline 500
Circulating Oils
Product Description
The Mobil Vacuoline 500 Series family of products provides a versatile lubricant source for a wide range of
industrial equipment. The Mobil Vacuoline 500 Series of lubricants are high performance heavy duty circulating
oils designed for the demands of No-Twist Rod mills, however their all round performance makes them a excellent
choice for circulation systems lubricating gears and bearings. Mobil Vacuoline 500 Series are designed to meet
the critical requirements of the Morgan Construction Company’s high speed No-Twist Rod Mills, as well as the
circulation oil requirements of Danielli rod mills.
They are formulated from high quality base stocks and a proprietary additive system to provide superior wettability,
extra oil retention and thin film protection against rust and corrosion. Mobil Vacuoline 500 gives excellent
resistance to oxidation and thermal degradation, and a high level of protection against wear. They possess
excellent demulsibility that permits water and other contaminants to separate readily from the oil in the system
reservoir. The Mobil Vacuoline 500 Series are available in six viscosity grades.
Features and Benefits
The Mobil Vacuoline 500 Series family of products is well known and highly regarded world-wide based on their
outstanding performance and the Research and Development expertise and global technical support which
stand behind the brand. The highly versatile performance of Mobil Vacuoline 500 Series oils, has made them
the choice of many users around the world for many decades.
Mobil Vacuoline 500 series are designed for lubrication of circulation systems of No-Twist Rod Mills, industrial
and marine gearboxes, hydraulic systems plus a wide variety of ancillary equipment.

Multiple application capability Inventory Savings
These oils are intended primarily for the lubrication of plain bearings, roller bearings, parallel shaft and bevel
gearing. They are suitable as multipurpose lubricants in systems not subject to shock loading and which do not
require extreme pressure performance. The Mobil Vacuoline 500 series possess good demulsibility that is
retained under conditions of severe water contamination. Mobil Vacuoline 500 series are used in applications
using splash, bath and ring oil arrangements and all other application methods involving pumps, valves and
1 of 3
auxiliary equipment. They are recommended for use in hydraulic systems where higher viscosity oils are specified.
They are particularly resistant to the effects of prolonged high temperature exposure and performwell in circulating
systems with short oil residence times.
Typical applications include
• No Twist Rod Mills
• Moderate duty spur, bevel, helical and herringbone gear units
• Circulating systems
• Mobil Vacuoline 525, 528, 533 can also be used in hydraulic systems employing gear, vane, radial and
axial piston pumps where high viscosity anti-wear hydraulic fluids are required.
• Certain compressors and vacuum pumps handling air and inert gases provided the discharge temperatures
do not exceed 150oC , not suitable for breathing air compressors
