Application:
Shell Spirax S4 CX 50 is a high-performance transmission and final drive oil developed to meet the demanding lubrication requirements of heavy-duty off-highway equipment. It is engineered for trouble-free operation and maximum reliability throughout the equipment’s lifetime, making it ideal for powershift transmissions, final drives, and oil-immersed brakes in construction, mining, and similar applications.
Performance Features & Benefits:
- Consistent Friction Performance: Provides reliable, stable friction characteristics with advanced metallic and non-metallic materials used in modern systems, ensuring minimal clutch slippage, smooth brake operation, and optimal transmission performance.
- Superior Anti-Wear Protection: Shear-stable SAE 50 viscosity grade ensures maximum protection for heavily loaded components, particularly in final drive systems and differentials.
- Low-Temperature Properties: Formulated to meet low-temperature viscosity requirements for superior protection during cold starts and low-temperature operations.
- Long Oil Life & Optimal Mechanical Performance: Offers wide-ranging protection for critical components, including bronze friction discs, gears, and bearings under severe conditions.
- Oxidation Stability & Corrosion Protection: Contains inhibitors that effectively control oxidation and deposit formation, protecting both ferrous and non-ferrous metals and suppressing foaming for reliable operation.
Main Application Areas:
- Powershift transmissions
- Final drives
- Oil-immersed (wet) brakes in heavy-duty off-highway machinery
Specifications & Approvals:
- Caterpillar TO-4
- Suitable for applications requiring Allison C-4 type fluids
