Mobil Vactra No. 2
Mobil Vactra No. 2 is part of the Mobil Vactra Oil Numbered Series, a range of premium-quality slideway lubricants specifically developed for precision machine tools. These oils are formulated from high-quality base stocks and a carefully balanced additive system that provides controlled friction characteristics, corrosion protection and compatibility with aqueous metalworking fluids. The formulation helps improve machining accuracy, surface finish and overall equipment reliability.
One of the key advantages of Mobil Vactra No. 2 is its controlled friction performance. The advanced additive technology helps reduce stick-slip and chatter across a wide range of slideway material combinations. This allows smooth, uniform movement and supports improved machining precision and productivity.
Mobil Vactra No. 2 also provides excellent coolant separability. The oil separates readily from aqueous coolants, reducing cross contamination and helping extend the service life of both the coolant and lubricant. The formulation also offers strong adhesiveness to maintain lubrication on critical sliding surfaces.
Another important benefit is its rust and corrosion protection. Mobil Vactra No. 2 helps protect sliding surfaces from moisture and coolant exposure. The lubricant also provides good load-carrying capability and excellent lubricity, supporting improved machine accuracy and reduced wear.
Mobil Vactra No. 2 is recommended for horizontal slideways on small to medium-sized machine tools and for circulating systems in larger machines. It is also suitable for moderate-duty hydraulic service and for lubrication of ball screws, linear guides and headstocks. The oil can be applied manually, through forced-feed lubricators or by circulation systems.
Physical characteristics include ISO VG 68 viscosity grade with a kinematic viscosity of approximately 68 mm²/s at 40°C. Mobil Vactra No. 2 has a flash point of approximately 228°C and a pour point of approximately −9°C. The lubricant provides smooth machine movement, excellent surface protection and reliable slideway performance.
