Shell Omala S4 WE 680 - Synthetic oils based on polyglycols with very good low temperature characteristics, thermal and oxidative stability and anti-friction properties. Reduce friction and increase the efficiency of highly loaded gearboxes. They are used primarily for lubricating worm gears (friction pair “bronze-steel”), as well as for circulating lubrication of bearings (for example, calenders of paper machines).
Application area
• High speed / heavy duty industrial transmissions
• Worm gears
• Bearings and circulating systems of installations such as calendars, where the working temperature of the oil in the volume can reach 200 ° C
Shell Omala S4 WE 680 oils are not recommended for the lubrication of gears made of bronze alloys containing aluminum.
Advantages
• Extremely high viscosity index
Due to the synthetic base with a high viscosity index, the introduction of special additives that increase this indicator is not required. Viscosity remains high at elevated temperatures, which provides a reliable oil film in the most severe conditions.
• Excellent antiwear properties
Due to slight wear, losses associated with maintenance are reduced. Oils show very good results when evaluating their properties in a roller bearing (FE-8 method).
• Extremely low friction
The efficiency of the worm gear is higher than on other oils, this provides a more efficient power transfer, reduces energy consumption and operating costs.
• Excellent protection against scoring in a pair of steel-steel and anti-wear characteristics in a pair of steel-bronze Ensure reliable operation of the equipment without breakage.
• High thermal and oxidative stability
Resistant to the formation of hazardous oxidation products, so that the oil remains clean.
• Low pour point
Provides effective lubrication even at low starting temperatures.
