Key Features and Benefits:
- Extended Oil Life: The use of highly stable synthetic base oils, combined with robust rust and oxidation inhibitors, provides excellent oxidation and hydrolytic stability. This allows for longer maintenance intervals compared to conventional mineral oil-based products.
- Excellent Wear and Corrosion Protection: Formulated to deliver superior anti-wear performance, Shell Morlina S4 B 220 offers high levels of protection for plain and rolling element bearings, as well as moderately loaded gearboxes. It also provides outstanding rust and corrosion protection for all metal surfaces.
- Enhanced System Efficiency: The superior low-temperature performance and reduced variation in viscosity with increasing temperature, compared to mineral oil-based products, provide better lubrication at low start-up temperatures. This contributes to energy savings through reduced pumping and flow losses during normal operating conditions. Additionally, rapid water shedding and efficient air release properties help maintain critical oil films between loaded components.
Applications:
- Moderate Load Applications: Recommended for systems that include moderately loaded gearboxes, worm gear drives, vacuum pumps, and gearboxes with internal backstops subjected to extreme temperature variations.
- Lubricated-for-Life Systems: Suitable for use in certain ‘lubricated-for-life’ systems due to its long oil life.
- Bearing and Circulating Oil Systems: Ideal for systems containing plain or rolling element bearings, including those with highly loaded bearings commonly found in cement or quarrying applications.
