Description
Castrol Magna™ MGX circulating oil range are based upon high quality solvent-refined mineral oils and performance
enhancing additives. The Magna MGX range provides high oil film strength, outstanding rust protection, antiwear, antiscuff,
anti-oxidation and water separating properties.
Application
Magna MGX circulating oils are engineered for use in MORGOIL™ back-up roll bearing systems such as those
manufactured by Morgan Construction Company, Danieli, SMS Demag and others. These oils meet or exceed:
Morgoil Lubricant Specification Rev. 1.1 (27 Jan 2005)
Danieli Standard 0.000.001 Rev 14
Magna MGX 88 is also recommended for high speed No-Twist™ Rod Mills with a single lubricant circulating system.
In No-Twist Rod Mills having two lubricating systems, the higher viscosity grades are used in the low speed roughing
stands and the lighter grades in the higher speed finishing stands.
The higher viscosity grades of this product are also very suitable to be used as paper machine lubricants, due to the high
thermal/oxidative stability, as well as the outstanding performance in rust protection, water separation and wear/scuffing
protection. In such applications, it functions as a joint bearing/gear lubricant in most lubricating points, including the rolling
bearings of the driers.
Magna MGX circulating oils are also suitable for use on other primary mill and mini-mill bearing application systems.
Advantages
High viscosity indices.
Excellent oxidation stability permits extended oil life.
Exceptional hydrolytic stability in presence of moisture contamination.
Excellent filterability in wet conditions.
Excellent water separation properties.
Good rust protection properties and low copper corrosion tendency.
High film strength and outstanding anti-wear properties to provide high protection against bearing wear and gear
scuffing under severe loading conditions.
Low carbon forming tendency minimises bearing deposits and helps to maintain oil cleanliness under severe
operating conditions.
Efficient filtration with all types of filters, including those using fuller’s earth as filtering medium.
