Product description
Mobil Vactra Oil No.4 are premium quality oils specifically designed to meet the exact precision and part surface quality requirements required by today's high efficiency machine tools. It is formulated with high quality base oils and performance-balanced low friction feature, superior protection against corrosion and an additive system that provides resistance to foam formation. The original and advanced technology additive package prevents retained-shifted motion and noise in the thin oil film formed under boundary lubrication conditions. In this way, smooth and uniform movement of mechanical parts at design speed is achieved. Mobil Vactra Oil No.4, water in cooling systems
It is formulated to keep the corrosive effect of high pH coolant on lubricated surfaces to a minimum while it is easily separated from the mixed coolant.
The base oil and additive package has been carefully selected for the protection of the slides and at the same time, it has been ensured to have superior filterability. This is important because the low oil flow or the clogging of the oil filters causes stuck-slip motion and noise, increasing wear. The spreading of the oil on the surface and the adhesive additives it contains counteract the escape of oil from the static load on the slide surfaces when the machine is not running.
Features and Benefits
Mobil Vactra Oil No.4 has been developed and specifically designed to meet the stringent demands of skids operating under the harshest conditions while providing additional machine protection, while meeting the requirements for the lubrication of other parts in equipment. These exhibit excellent lubrication and load-bearing performance, making a significant contribution to the production of quality parts. The unique oxidation resistance and thermal stability properties of these oils contribute to the cleaning of the machines, provide the necessary filterability and eliminate the need for frequent machine maintenance. Mobil Vactra Oil No.4 water and water-containing refrigerant
It has the feature of separating from liquids very easily, thus preventing mutual contamination and increasing the life and performance of both oil and coolant.

Usage places
Mobil Vactra Oil No.4 are oils suitable for both slide lubrication and machine tool hydraulic systems under normal service conditions. These oils are suitable for all combinations of cast iron, steel and non-metal slide materials. Mobil Vactra Oil No. It can be applied with 4 hands and with forced lubricants or central lubrication system. The extreme pressure (EP) feature makes these oils usable for all types of gears in machine tools. These oils should not be used in central lubrication systems where the oil temperature exceeds 66ºC.
Mobil Vactra Oil No. Recommended for small and medium machine tools with 2 horizontal slides. It is also suitable for centralized lubrication systems in large machines.
Mobil Vactra Oil No. 4 mainly recommended for large machines where slide pressures are high or high precision is required. This oil is also recommended for vertical or curved skids where oil flow is a problem.
• Mobil Vactra Oil No.4 is used for the lubrication of ball screws, linear guides, turning centers, transmission screws, spur and bevel gears and lightly loaded worm gears.
• The service life of water-based coolants is shortened due to traditional mineral oil contamination
