Mobil Vactra Named Oils
Mobil Industrial, Egypt
General Purpose Machine Oils
Mobil Vactra Oil Named and Double Lettered Series oils are formulated from selected chemically stable base oils. Mild antiwear and improved film-strength additives enable these oils to adhere strongly to metal surfaces and provide protection against welding and scoring under thin-film conditions. An effective inhibitor prevents rust and corrosion. All seven grades contain a pour point depressant which lowers the minimum temperature at which they may be used.
Features and Benefits
- Excellent wear protection under boundary lubrication conditions
- Good rust and corrosion protection
- Multipurpose, multiservice capability
- Economical operation
- Wide acceptance by machinery builders
- Non-zinc additive technology
Mobil Vactra Oil Named and Double Lettered Series are formulated for enclosed gears and bearings in industrial applications where a general-purpose oil is recommended. They provide excellent lubrication of plain and antifriction bearings. They are particularly suited for general machine tool lubrication or other industrial applications where the lubricant is applied intermittently.Mobil Vactra Oil Named and Double Lettered Series oils also are recommended for moderate-duty circulation and hydraulic systems where high leakage rates necessitate frequent make-up or where contamination requires frequent change-outs. In such service, these oils offer an economic advantage over premium-quality turbine and circulating oils.Mobil Vactra Oil Named and Double Lettered Series products should not be used where bulk oil temperatures exceed 66 ºC (150 ºF) or where the oil is expected to remain in service for indefinite periods.
