Features

The Mobil Vactra Oil Numbered Series has been developed and specifically designed to provide an extra margin of machinery protection by satisfying the stringent demands of slide ways. The oils exhibit excellent lubricity and load-carrying performance contributing significantly to improving the production of quality parts. The Mobil Vactra Oil Numbered Series provides separability from many water and aqueous coolants reducing the potential negative effects of cross contamination which helps to enhance the service life and performance of both the lubricant and coolant.

Advantages and Potential Benefits

Feature Advantages and Benefits
Controlled Frictional Characteristics Helps eliminate stick slip; allows consistently accurate machining
Multi-material Capabilities Suitable for a wide range of way material combinations allowing for product consolidation
Water and Aqueous Coolant Separability Helps improve the life and performance of many aqueous coolants
Adhesiveness Prevents removal of lubricant from critical surfaces
Long Term Rust and Corrosion Protection Helps reduce the deterioration of sliding surfaces in the presence of water and aqueous coolants

Applications

Mobil Vactra Oil Numbered Series products are recommended for the lubrication of machine tool slideway systems. They are designed for use with combinations of cast iron, steel and non-metallic way materials. Mobil Vactra Oil Numbered Series may be applied by hand, forced-feed lubricator or in flood application by circulation system.

  • Mobil Vactra Oil No. Series of products are suitable for use in applications that require Fives Cincinnati specifications P53, P47, and P50.
  • Mobil Vactra Oil No. 1 and No. 2 are recommended for horizontal slideways on small to medium size machine tools. They are also suitable for circulating application in large machines and as a moderate duty hydraulic fluid.
  • Mobil Vactra Oil No. 3 and No. 4 are normally recommended for large machines where way pressures are high and good precision is required. They are also recommended for vertical and inclined slideways where drain-down can be a problem and for moderate service machine tool gear drive mechanisms.
  • Mobil Vactra Oil Numbered Series can be used for lubrication of ball screws, linear guides, headstocks, translating screws.
  • Mobil Vactra Oil Numbered Series is recommended for applications where oil contamination of the aqueous coolants shortens coolant batch life.
