As a leading high-performance synthetic lubricant, Shell Morlina S4 B 320 provides superior protection against wear and corrosion. This oil promotes system efficiency in "lubricated for life" systems, moderately loaded gearboxes, and highly loaded bearing systems such as those in cement and quarrying operations. Shell Morlina S4 B 320 is designed to handle extreme temperatures, low and high, and frequent temperature fluctuations without compromising its efficiency or effectiveness.

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 oil-based 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 including moderately loaded gearboxes, operating under severe conditions such as low or high temperatures or with wide temperature variations.

Lubricated for life system
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.

Frequently asked questions

Find answers to common questions about our products and services

  • This oil is designed for moderately loaded gearboxes, plain and rolling element bearings, circulating oil systems, and highly loaded bearing systems such as those found in cement and quarrying operations. It is also suitable for certain "lubricated-for-life" systems where extended oil life is required.

  • The synthetic base oil formulation delivers better anti-wear protection for bearings and gearboxes, superior low-temperature start-up performance, and a reduced change in viscosity as temperature rises compared to mineral oil-based products. These properties translate to improved component life, better energy efficiency through reduced pumping and flow losses, and extended maintenance intervals.

  • It is specifically engineered to operate reliably under both low and high temperatures as well as frequent temperature fluctuations without compromising performance. The superior low-temperature fluidity ensures adequate lubrication during cold start-ups, while strong oxidation and thermal stability prevent the formation of harmful deposits at high operating temperatures.

  • ISO VG 320 is a high-viscosity grade, meaning this oil maintains a robust, thick film suited for heavily loaded or higher-temperature bearing and gearbox applications. If your equipment manufacturer specifies an ISO VG 320 grade oil — or one meeting ISO 12925-1 Type CKS — this product is formulated to meet that requirement. Always confirm with your equipment's OEM specifications before use.

  • Shell Morlina S4 B 320 meets the ISO 12925-1 Type CKS specification and carries approvals and recommendations for a range of equipment, including Alfa Laval Group D gearbox applications, Aerzen Maschinenfabrik GmbH blower applications, Baltimore Aircoil gearboxes, Cincinnati Machine various P applications, David Brown Table H applications, Emerson Power Transmission, GEA Westfalia Separator GmbH, Renold Gears, Sharpe E-series worm gear reducers, and Winsmith worm gear reducers.

  • Rapid water separation and quick air release help the oil maintain critical lubricating films between loaded components even in wet or aerated conditions. This reduces the risk of oil film breakdown, minimizes corrosion from water contamination, and supports overall system reliability and efficiency in circulating oil systems.

Key Features
