Mobil Vactra NR 4 20L

The Mobil Vactra Oil Numbered series consists of high-quality slideway oils specifically developed to meet the precision and equipment protection requirements of precision machine tools and to provide good separation from water-based coolants. The Mobil Vactra Oil Numbered series is carefully formulated from high-quality base oils, with performance balanced by an advanced additive system that delivers controlled friction characteristics, compatibility with water-based metalworking fluids, and corrosion protection for both components and equipment. The unique additive package provides exceptional friction performance across a wide range of machining materials, including steel-on-steel and steel-on-polymer, by minimizing stick-slip motion and vibration caused by inadequate oil film formation. This enables smooth, consistent movement at design feed rates, helping to increase machine productivity and precision by extending tool life and improving surface finish. The Mobil Vactra Oil Numbered series is optimized to ensure separation from most water-based coolants while reducing the corrosive effects of highly alkaline coolants on lubricated surfaces.
