Mobil Vactra Oil No. 4

Mobil Vactra No 4

The Mobil Vactra Oil Numbered Series are premium-quality slideway lubricants specifically designed to meet the requirements for accuracy, aqueous coolant separability, and equipment protection of precision machine tools. The Mobil Vactra Oil Numbered Series are carefully formulated from high-quality base stocks and performance balanced with an advanced additive system that provides controlled frictional properties, outstanding aqueous metal working fluid compatibility and corrosion protection of parts and equipment. The unique additive package provides exceptional frictional properties on a wide variety of way materials, including steel on steel and steel on polymer, reducing stick-slip and chatter. The Mobil Vactra Oil Numbered Series have been optimized to provide excellent separability from aqueous coolants while minimizing the corrosive effects of high pH coolants on lubricated surfaces.

Advantages and Potential Benefits:

• Exceptional frictional characteristics helps eliminate stick slip and allows consistently accurate machining

• Multi-material capabilities allows for product consolidation

• Excellent separability helps improve the life and performance of 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

• Hydraulic and gear capabilities allows for product consolidation


• Mobil Vactra Oil No. 2: Horizontal slideways on small to medium size machine tools; also suitable for circulating application in large machines and as moderate duty hydraulic fluids

• Mobil Vactra Oil No. 4: Large machines where way pressures are high or good precision is required as well as vertical and inclined slideways where drain-down can be a problem and for moderate service machine tool gear drive mechanisms

• Ball screws, linear guides, headstocks, translating screws

• Applications where conventional mineral oil contamination of the aqueous coolants shortens coolant batch life
