Shell Morlina S4 B 320


Shell Morlina S4 B 320 Is a high-performance lubricant.


Advanced Bearing & Circulating Oils

Shell Morlina S4 B oils are high performance synthetic bearing and circulation lubricants, based on high performance base fluids. They offer outstanding lubrication performance under severe operating conditions, including improved energy efficiency and long service life even in severe operating conditions.


Performance, Features & Benefits


Long oil life – maintenance saving


  • The use of highly stable synthetic base oils in conjunction with a robust rust and oxidation inhibitor package helps provide excellent oxidation and thermal stability. This provides Shell Morlina S4 B with extending maintenance capability compared to conventional oils.
  • In addition it resists the formation of harmful products of oxidation at high operating temperatures, to help maintain system cleanliness and therefore reliability of the equipment.


Excellent wear and corrosion protection


  • Shell Morlina S4 B has been formulated to provide excellent anti-wear performance and provides high levels of wear protection for plain and rolling element bearings and moderately loaded gearboxes, compared to mineral oilbased products. This helps provide superior gear and bearing component life.
  • In addition it also provides outstanding rust and corrosion protection of all metal surfaces.


Enhancing system efficiency


  • Shell Morlina S4 B can help improve the efficiency of lubrication in bearing and circulating systems. The superior low temperature performance and reduced change in viscosity with increase in temperature in comparison to mineral oilbased products provides better lubrication at low start-up temperatures and the opportunity for energy savings through reduced pumping and flow losses during normal operating conditions.
  • Rapid water shedding and air release properties further enhance the efficiency of the lubrication system by helping maintain critical oil films between loaded components.


Main Applications


Severe operating conditions
  • Shell Morlina S4 B is recommended for systems incuding moderately loaded gearboxes, operating under severe conditions such as low or high temperatures or with wide temperature variations.


Lubricated for life systems


  • The long oil life of Shell Morlina S4 B makes is suitable for use in certain ‘lubricated-for-life’ systems.


Bearing and circulating oil systems


  • Suitable for use in systems containing plain or rolling element bearings, including those highly loaded bearings found in such as those found in cement or quarrying applications.
