Mobilube XFD 50
High Performance Drivetrain Lubricants
Mobilube™ XFD 50 and 60 are high performance drivetrain lubricants engineered specifically to provide optimum component life when used as recommended in Caterpillar final drives and axles. They are formulated from advanced base oils and the latest additive technology to protect bearings and gears from premature failure due to fatigue. These lubricants deliver excellent performance in heavy-duty commercial axles and final drives where extreme pressures and shock loading are expected. They provide exceptional chemical and thermal stability at elevated bulk oil temperatures generated under heavy loads and/or high ambient temperatures.
Mobilube XFD Series have been extensively field tested in Caterpillar off-highway heavy trucks and bulldozers over a wide range of ambient temperatures and operating in severe conditions with a recommended drain interval up to 4,000 hours for off-highway haulers.
Features and Benefits
Demands for higher productivity, more severe operating conditions, and larger capacity equipment put severe stress on axles and final drive components. In severe applications, TO-4 lubricants may be limited in terms of wear protection in heavily loaded final drives due to their need to also serve the frictional requirements of clutches in heavy-duty transmissions. For optimum durability and performance, Mobilube XFD gear lubricants can be relied on to maintain productivity and minimize maintenance costs between scheduled service intervals in extreme applications. The key benefits include:
|Features||Advantages and Potential Benefits|
|Improved extreme pressure (EP) performance versus TO-4 fluids||Increased load and shock carrying ability with reduced premature failures and operating costs|
|High oxidation and thermal stability||Longer oil life, reduced deposits, and extended component life|
|Excellent protection against copper corrosion and rust||Extended component life and lower maintenance costs|
|Wide temperature capability||Simplifies inventory and reduces need for seasonal change-outs|
|Good compatibility with seals and conventional drive train lubricants||Reduces leakage and contamination from external sources|
|Eliminates or reduces foaming||Maintains film strength for reliable wear protection|
- Heavy-duty axles and final drives used in trucks and bulldozers built by Caterpillar
- Off-highway industries including: construction, mining, and quarrying
