Typical characteristics

Manufacturer's description

High-performance transmission oil for off-road equipment and final drives. Shell Spirax S4 CX 50 is formulated to give operators trouble-free equipment operation and maximum reliability throughout its service life. Spirax S4 CX 50 meets the oil requirements for use in the modern transmissions, final drives and oil-immersed brakes fitted to heavy off-road equipment.

Applications

• Shell Spirax S4 CX 50 is recommended for use in heavy off-road equipment produced by the world's leading manufacturers, including Caterpillar, Komatsu and Komatsu-Dresser, and in transmissions produced by Eaton, Eaton Fuller, ZF, Dana and Rockwell, in:

Performance & benefits

• Frictional performance and material compatibilityConsistent, highly reliable performance when used with the metallic and non-metallic materials found in modern systems. Minimal clutch slip, smooth and quiet brake operation, and trouble-free transmission operation.
• Anti-wear protectionThe shear stability of the SAE 50 viscosity grade provides the best protection for heavily loaded components, particularly in highly loaded final drive systems.
• Low-temperature characteristicsThe product has been formulated to meet low-temperature viscosity and fluidity requirements, thereby providing superior component protection both at start-up and during operation at low temperatures.
• Optimum mechanical performance and long service lifeThe product provides broad protection for critical components, such as the bronze friction discs in power transmissions and the gears in final drives and differential units.
• Oxidation stabilityContains inhibitors that control oxidation and deposit formation. Protects both ferrous and non-ferrous metals against corrosion. Suppresses foam formation. Has improved low-temperature flow properties that increase efficiency.
• Suitable for applications requiring Allison C-4 type fluids
