Shell Morlina S2 BL 10
Shell Morlina S2 BL 10 is a high-performance low viscosity bearing and circulating oil specifically developed for high-speed machine tool applications. Formulated using high-quality solvent refined mineral base oils combined with zinc-free additive technology, the lubricant is designed to provide reliable lubrication and extended performance in high-speed spindles and precision machine components. The product is particularly suitable for applications where low viscosity oils are required to support efficient operation and minimise heat build-up during high-speed operation.
One of the key advantages of Shell Morlina S2 BL 10 is its excellent oxidation stability, which helps extend oil service life and reduce maintenance requirements. Industrial machinery operating at high speeds can generate significant heat and exposure to air, water and metal catalysts. The oil is formulated with a well-proven rust and oxidation inhibitor package that helps resist oxidation and maintain lubricant performance over extended operating periods. This helps minimise sludge formation and oil degradation, supporting longer oil drain intervals and lower operating costs.
Shell Morlina S2 BL 10 also provides reliable wear and corrosion protection for bearings and circulating lubrication systems. The specially selected additive technology delivers efficient anti-wear performance without reacting with softer bearing metals, ensuring compatibility with sensitive machine components. This helps maintain machine reliability and extends the operational life of bearings and other precision parts. In addition, the additive system enhances the oil’s natural corrosion protection properties, helping safeguard equipment against rust and degradation.
The low viscosity formulation of Shell Morlina S2 BL 10 plays an important role in maintaining system efficiency in high-speed equipment. The carefully selected base oils promote smooth running of machine elements by reducing friction and minimising heat build-up caused by mechanical energy losses. This helps improve machine performance and maintain consistent operating conditions in high-speed spindle systems.
Shell Morlina S2 BL 10 is suitable for a wide range of industrial lubrication applications including machine bearing and circulating lubrication systems. It is particularly recommended for high-speed spindle lubrication in machine tools where low viscosity oils are required to maintain efficient operation and accurate machine performance. These oils are commonly used in high-speed frames and automated machine tools operating under demanding conditions.
The product meets key industry specifications including Fives Cincinnati P-65 for ISO VG 2 oils and Fives Cincinnati P-62 for ISO VG 5 and ISO VG 10 grades. These approvals confirm the oil’s suitability for precision machine tool lubrication and high-speed industrial applications.
Physical characteristics include a kinematic viscosity of approximately 10 mm²/s at 40°C and 2.3 mm²/s at 100°C. The oil has a density of approximately 881 kg/m³ at 15°C, a flash point of approximately 150°C and a pour point of approximately –30°C. These properties support reliable lubrication performance across a range of high-speed operating conditions.
