Mobil Vactra Slideway 220
Mobil Vactra Slideway 220 is part of the Mobil Vactra Slideway Series, a range of high-quality lubricants specifically designed for linear motion guides, ball screws and slideways of high-precision machine tools. The formulation uses high-quality base oils and an advanced additive system to provide controlled friction characteristics, coolant compatibility and corrosion protection. This helps ensure smooth, accurate machine movement and improved machining performance.
One of the key advantages of Mobil Vactra Slideway 220 is its controlled friction performance. The additive system reduces stick-slip and chatter across a wide range of slideway material combinations including steel-on-steel and steel-on-polymer. This allows smooth, uniform motion and supports high machining accuracy and improved surface finish.
Mobil Vactra Slideway 220 also provides excellent adhesiveness. The lubricant resists wash-off by metalworking fluids and remains on critical surfaces, helping prevent abnormal noises, increased sliding resistance and loss of machining precision. This supports consistent machine performance even in applications with high coolant wash.
Another important benefit is its coolant separability and corrosion protection. The oil separates readily from aqueous coolants, helping extend coolant life and maintain machine accuracy. It also provides long-term rust and corrosion protection for sliding surfaces exposed to moisture or coolant contamination.
Mobil Vactra Slideway 220 is recommended for lubrication of machine tool slideway systems, ball screws, linear guides and translating screws. It is suitable for horizontal and vertical slideways, large precision machines and applications where strong film strength and load-carrying capability are required. The oil can be applied manually, through forced-feed lubricators or circulation systems.
Physical characteristics include ISO VG 220 viscosity grade with a kinematic viscosity of approximately 218.4 mm²/s at 40°C. Mobil Vactra Slideway 220 has a flash point of approximately 255°C and a pour point of approximately −12°C. The lubricant provides strong adhesion, excellent friction control and reliable protection for precision slideway applications.
