Mobil Vactra Slideway 68
Mobil Vactra Slideway 68 is part of the Mobil Vactra Slideway Series, a range of high-quality lubricants developed for linear motion guides, ball screws and slideways of high-precision machine tools. These lubricants are formulated using high-quality base stocks and an advanced additive system that provides controlled friction characteristics, coolant compatibility and corrosion protection. The formulation supports smooth machine movement, improved machining accuracy and extended equipment life.
One of the key advantages of Mobil Vactra Slideway 68 is its controlled friction performance. The additive system reduces stick-slip and chatter across a wide range of way materials including steel-on-steel and steel-on-polymer combinations. This allows smooth, uniform motion and helps improve surface finish and machining precision.
Mobil Vactra Slideway 68 also provides excellent adhesiveness. The lubricant resists wash-off from aqueous metalworking fluids and remains on critical sliding surfaces. This helps prevent abnormal noise, increased sliding resistance and reduced machining accuracy, ensuring consistent machine performance.
Another important benefit is its coolant separability and corrosion protection. The oil separates effectively from aqueous coolants, helping extend coolant life and reduce contamination. It also provides long-term rust and corrosion protection for sliding surfaces exposed to moisture and coolant.
Mobil Vactra Slideway 68 is recommended for lubrication of machine tool slideways, ball screws, linear guides and translating screws. It is suitable for horizontal slideways on small to medium-sized machines and for circulating applications in larger equipment. The oil can be applied manually, by forced-feed lubricators or through circulation systems.
Physical characteristics include ISO VG 68 viscosity grade with a kinematic viscosity of approximately 70.5 mm²/s at 40°C. Mobil Vactra Slideway 68 has a flash point of approximately 245°C and a pour point of approximately −12°C. The lubricant provides excellent friction control, strong adhesion and reliable protection for precision slideway applications.
