Shell Morlina S2 BL 5 is a high-performance low viscosity bearing and circulating oil designed for precision lubrication in high-speed machine tool applications. Developed using Shell Gas-to-Liquid (GTL) technology combined with zinc-free additive systems, the oil delivers excellent performance in demanding high-speed environments. Its specialised formulation provides efficient lubrication while minimising friction and heat generation, helping maintain stable operation in modern manufacturing equipment and high-speed spindle systems.
One of the key advantages of Shell Morlina S2 BL 5 is its exceptional oxidation resistance, which contributes to extended lubricant life and reduced maintenance requirements. High-speed machinery can expose lubricants to elevated temperatures and harsh operating conditions. The oil incorporates a proven rust and oxidation inhibitor package that provides strong resistance to oxidation, particularly in hot and wet environments. It is also resistant to degradation caused by metal catalysts such as copper. These characteristics help maintain oil stability over extended operating periods, reduce sludge formation and prolong service intervals.
Shell Morlina S2 BL 5 also provides reliable wear and corrosion protection for machine components. The carefully balanced additive package delivers effective anti-wear performance without reacting with softer bearing metals. This compatibility helps ensure reliable operation of sensitive machine parts and enhances the durability of bearings and precision components. In addition, the additive system improves the oil’s natural corrosion protection properties, helping prevent rust formation and extend equipment life.
The oil’s low viscosity formulation plays a critical role in maintaining system efficiency within high-speed equipment. The carefully selected base oils promote smooth movement of machine elements by reducing friction and minimising heat build-up caused by mechanical energy losses. This helps improve operational efficiency and ensures stable performance in high-speed spindle applications where precise lubrication is essential for maintaining accuracy and machine reliability.
Shell Morlina S2 BL 5 is suitable for use in machine bearing and circulating lubrication systems that utilise oil-lubricated plain and rolling element bearings. It is particularly recommended for high-speed spindle lubrication in machine tools and automated manufacturing equipment where very light viscosity oils are required to support high rotational speeds and precision performance. These applications include high-speed frames, automated production lines and precision machining systems.
The product meets the requirements of the Fives Group Cincinnati P-62 specification for very light spindle oils, confirming its suitability for demanding machine tool lubrication applications.
Physical characteristics include a kinematic viscosity of approximately 5 mm²/s at 40°C and 1.9 mm²/s at 100°C, with a viscosity index of approximately 120. The oil has a density of approximately 806 kg/m³ at 15°C, a flash point of approximately 115°C and a pour point of approximately –42°C. These properties support reliable lubrication performance across a wide range of high-speed operating conditions.
