Shell Morlina S4 B 150
Shell Morlina S4 B 150 is a high-performance synthetic bearing and circulating oil designed to provide advanced lubrication performance for demanding industrial machinery. Manufactured using high-quality synthetic base fluids combined with carefully selected additive technology, the oil delivers exceptional reliability, improved energy efficiency and extended service life compared with conventional mineral oil-based lubricants. The product is developed to support modern industrial equipment that requires high levels of lubrication performance under challenging operating conditions.
A key advantage of Shell Morlina S4 B 150 is its outstanding oxidation and hydrolytic stability, which helps extend oil life and reduce maintenance requirements. Industrial lubrication systems can operate at high temperatures and in environments where water contamination may occur. The highly stable synthetic base oils, combined with robust rust and oxidation inhibitor additives, provide excellent resistance to oxidation and degradation. This helps maintain lubricant performance for longer operating intervals while preventing the formation of harmful oxidation products that could impact equipment reliability.
Shell Morlina S4 B 150 also provides excellent wear and corrosion protection for bearings and circulating lubrication systems. The advanced additive system helps protect both plain and rolling element bearings from wear, ensuring reliable operation even in moderately loaded gearboxes and bearing systems. The lubricant forms a strong protective oil film between metal surfaces, helping reduce friction and extend the service life of mechanical components. In addition, the formulation offers outstanding protection against rust and corrosion across a wide range of metal surfaces.
Another important benefit of Shell Morlina S4 B 150 is its ability to enhance system efficiency and support energy savings. Compared with conventional mineral oils, the synthetic formulation provides improved low temperature performance and reduced viscosity variation across different operating temperatures. This ensures better lubrication during start-up conditions and reduces pumping losses during normal operation. As a result, equipment can operate more efficiently while potentially lowering overall energy consumption.
The oil also offers excellent filterability, rapid water shedding and efficient air release properties. These characteristics help maintain clean lubrication systems by reducing contamination and ensuring that air and water can be separated effectively from the oil. Maintaining clean oil helps ensure reliable lubrication performance and protects sensitive machinery components from damage.
Shell Morlina S4 B 150 is suitable for a wide range of industrial applications including bearing and circulating oil systems containing plain or rolling element bearings. It can also be used in moderately loaded gearboxes, worm gear drives, vacuum pumps and systems subject to wide temperature variations. The lubricant is particularly suitable for heavy industrial environments such as cement plants, quarrying operations and other applications requiring reliable high-performance lubrication.
The product meets or exceeds key industry standards including ISO 12925-1 Type CKD, ANSI/AGMA 9005 and DIN 51517-3 CLP. It is also approved by major equipment manufacturers including Siemens/VAI Morgan “Morgoil®”, Voith Paper, Valmet Paper and Stäubli gearboxes.
Physical characteristics include a kinematic viscosity of approximately 150 mm²/s at 40°C and 21 mm²/s at 100°C with a viscosity index of approximately 158. The oil has a density of approximately 850 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.
