PRODUCT DESCRIPTION
Synthetic Machine Oils excel as top-tier industrial extreme-pressure gear and bearing lubricants. They’re the prime choice for situations demanding high loads, elevated temperatures, and the need to ward off water contamination. Syn Machine Oils stand out due to their exceptional anti-friction qualities, delivering peak performance in various applications, including bearings, steel gear transmissions, and steel/phosphor bronze gear units.
These remarkable Syn Machine Oils harness the power of full synthetic polyalphaolefin and ester fluids, fortified with specialized additives that elevate their resistance to oxidation, corrosion, rust, and foam formation.
RECOMMENDATIONS
Syn Machine Oils are recommended where high load and high temperature conditions occur in:
- Lubrication of enclosed gear drives in industrial settings, whether via splash or circulation methods.
- Heavy-duty industrial equipment such as journals, plain and anti-friction bearings, chain drives, and slide guides.
- In lower viscosity grades, they are well-suited for use in rock drills, hydraulic systems, and automotive manual gearboxes that require API grades GL-1, GL-2 (obsolete), and GL-3 (obsolete).
Syn Machine Oils may also be recommended where service conditions are not severe.
CHARACTERISTICS
Syn Machine Oils have combined superior additives with the inherent protection of full synthetic base fluids ensuring ultimate protection for your machinery.
EXTREME PRESSURE / ANTI-WEAR. Minimal wear to all moving surfaces assures long service life for equipment. The tough tenacious oil films, under high load/stress conditions, resist the wiping-off tendencies whenever high sliding velocities occur between the mating teeth of gear units.
NON-CORROSIVE. Syn Machine Oils protect against corrosion to all common metals used in gears and bearings: steel, bronze and other copper alloys, nickel, chromium, cadmium, antimony, etc.
RUST INHIBITORS. Protect against rust development in systems where water contamination may occur.
DEMULSIBILITY. Quick water separation to assure effective lubrication is a special characteristic of Syn Machine Oils. This is a necessary requirement in the heavy duty operation in some steel mills where water contamination is difficult to avoid.
OXIDATION RESISTANCE. Resistance to oxidation at high temperature helps to reduce viscosity thickening and the other undesirable oxidation products such as gums, acidity development and deposition insoluble. Any of these products may otherwise result in premature gear failure and shortened equipment service life.
Vesta suggests that the equipment manufacturers’ recommendations for viscosity grade, performance requirements and general operating conditions should be checked prior to use.
