Shell Morlina S4 B 320
Shell Morlina S4 B 320 is a high-performance synthetic bearing and circulating oil designed to provide advanced lubrication performance for demanding industrial machinery and circulation systems. Manufactured using high-quality synthetic base fluids and advanced additive technology, the oil delivers outstanding reliability, improved energy efficiency and extended service life compared with conventional mineral oil-based lubricants. It is engineered to meet the lubrication requirements of modern industrial equipment operating under challenging conditions where long oil life and reliable component protection are essential.
One of the key advantages of Shell Morlina S4 B 320 is its exceptional oxidation and hydrolytic stability. Industrial lubrication systems often operate at high temperatures and may be exposed to water contamination during operation. The highly stable synthetic base oils combined with robust rust and oxidation inhibitor additives help resist oxidation and chemical degradation. This ensures the lubricant maintains its protective properties over extended operating intervals while reducing the formation of harmful oxidation by-products that could affect equipment reliability and cleanliness.
Shell Morlina S4 B 320 also provides excellent wear and corrosion protection for bearings and circulating lubrication systems. The advanced additive system delivers strong anti-wear performance that helps protect both plain and rolling element bearings as well as moderately loaded gearboxes. By forming a durable lubricating film between metal surfaces, the oil reduces friction and protects components from wear, helping extend the service life of bearings and gear components. In addition, the formulation provides outstanding rust and corrosion protection across all metal surfaces within the lubrication system.
Another important benefit of Shell Morlina S4 B 320 is its ability to enhance system efficiency and potentially reduce energy consumption. The synthetic formulation provides excellent low temperature performance and reduced viscosity variation as operating temperatures change compared with conventional mineral oils. This allows improved lubrication during cold start conditions and reduces pumping and flow losses during normal operation. As a result, equipment may benefit from improved operating efficiency and lower overall energy consumption.
Shell Morlina S4 B 320 also offers excellent filterability, rapid water shedding and efficient air release characteristics. These properties help maintain clean lubrication systems by allowing contaminants, air and water to separate effectively from the oil. Maintaining clean lubrication systems helps ensure consistent lubrication performance while protecting sensitive machinery components from damage caused by contamination.
The lubricant is suitable for a wide range of industrial applications including bearing and circulating oil systems containing plain or rolling element bearings. It is also recommended for moderately loaded gearboxes, worm gear drives, vacuum pumps and gear systems operating under varying temperature conditions. Shell Morlina S4 B 320 is commonly used in heavy industrial environments such as cement plants, quarrying operations and manufacturing facilities where reliable high-performance lubrication is required.
The product meets or exceeds key industry standards including ISO 12925-1 Type CKT specification, ANSI/AGMA 9005-E02 and DIN 51517 Part 3 (CLP oils). It is also approved by major equipment manufacturers including Siemens/VAI Morgan “Morgoil®”.
Physical characteristics include a kinematic viscosity of approximately 320 mm²/s at 40°C and 37 mm²/s at 100°C with a viscosity index of approximately 168. The oil has a density of approximately 854 kg/m³ at 15°C, a flash point of approximately 275°C and a pour point of approximately –42°C, supporting reliable lubrication performance across a wide range of industrial operating conditions.
