Mobil Vactra No. 1
Mobil Vactra No. 1 is part of the Mobil Vactra Oil Numbered Series, a range of premium-quality slideway lubricants specifically designed to meet the requirements of precision machine tools. These oils are formulated using high-quality base stocks and a carefully balanced additive system that provides controlled frictional properties, coolant separability and corrosion protection. The formulation helps ensure smooth motion, improved machining accuracy and extended equipment life.
One of the key advantages of Mobil Vactra No. 1 is its controlled friction characteristics. The advanced additive system helps reduce stick-slip and chatter across a variety of way material combinations, including steel-on-steel and steel-on-polymer surfaces. This allows smooth, uniform movement at design travel speeds and helps improve surface finish and tool life.
Mobil Vactra No. 1 also provides excellent coolant separability. The formulation is optimised to separate from aqueous metalworking fluids, reducing cross contamination and helping extend the service life of both coolant and lubricant. The oil also offers strong adhesiveness to prevent removal from critical sliding surfaces.
Another important benefit is its rust and corrosion protection. Mobil Vactra No. 1 helps protect machine components from moisture and high pH coolants, reducing wear and extending equipment life. The lubricant also provides good load-carrying performance to support precision machining operations.
Mobil Vactra No. 1 is recommended for lubrication of horizontal slideways on small to medium-sized machine tools. It is also suitable for circulating applications in large machines and can be used as a moderate-duty hydraulic fluid. The product is suitable for cast iron, steel and non-metallic way materials and can be applied manually, via forced-feed lubricators or circulation systems.
Physical characteristics include ISO VG 32 viscosity grade with a kinematic viscosity of approximately 32 mm²/s at 40°C. Mobil Vactra No. 1 has a flash point of approximately 216°C and a pour point of approximately −30°C. The lubricant provides smooth machine movement, excellent surface protection and reliable slideway performance.
