CASTROIL GEAR OIL

Differentials and Axles (gear oil) is a specialized lubricant designed specifically for transmissions, transfer cases, and differentials in automobiles, trucks, and other machinery. Unlike engine oil, which is primarily focused on lubricating and cooling, gear oil is formulated to handle the high-pressure conditions and extreme forces found in gear systems. Here’s a comprehensive overview of Differentials and Axles (gear oil):

Functions of Differentials and Axles (gear oil)

Lubrication:
- Reduces friction between gear teeth, ensuring smooth operation and preventing wear.
- Essential for extending the lifespan of gears and preventing mechanical failures.
Cooling:
- Helps dissipate the heat generated by the friction and movement of gears.
- Prevents overheating, which can lead to gear damage.
Protection:
- Contains additives that protect against corrosion, rust, and oxidation.
- Forms a protective film over metal surfaces to guard against metal-to-metal contact.
Shock Absorption:
- Cushions the impact of gear teeth engaging, reducing noise and vibration.
- Essential for heavy-duty and high-performance applications where gears undergo significant stress.
Cleaning:
- Includes detergents and dispersants that help keep the gear system clean by preventing the build-up of sludge and deposits.
- Helps in maintaining the efficiency and longevity of the gear system.

Additives in Differentials and Axles (gear oil)

To enhance its performance, Castroil Differentials and Axles (gear oil) contains various additives:

Extreme Pressure (EP) Additives:
- Provide extra protection under high-pressure conditions.
- Common in gear oils for heavy-duty applications.
Anti-Wear Additives:
- Reduce wear on gear surfaces, extending the lifespan of the gear system.
Anti-Foaming Agents:
- Prevent the formation of foam, which can reduce the effectiveness of the lubricant.
Corrosion and Rust Inhibitors:
- Protect metal surfaces from corrosion and rust, especially in moist or harsh environments.

Types of Differentials and Axles (gear oil)

Mineral-Based Gear Oils:
- Made from refined crude oil.
- Generally less expensive but may require more frequent changes.
Synthetic Gear Oils:
- Chemically engineered for superior performance.
- Provide better high-temperature stability, longer life, and improved performance in extreme conditions.

Differentials and Axles (gear oil) Grades

Castroil Differentials and Axles (gear oil) is classified by its viscosity, primarily using the SAE (Society of Automotive Engineers) grading system. Common grades include:

CASTROIL TRANSMAX FLUID SAE 75W-90
CASTROIL TRANSMAX FLUID SAE 80W-90
CASTROIL TRANSMAX FLUID SAE 85W-90
CASTROIL TRANSMAX FLUID SAE 85W-140
CASTROIL TRANSMAX FLUID SAE 90
CASTROIL TRANSMAX FLUID SAE 140

Maintenance and Replacement

Regular maintenance and replacement of Differentials and Axles (gear oil) are crucial for optimal performance. The recommended interval for changing gear oil varies depending on the vehicle, type of oil, and operating conditions, but it is generally advised to follow the manufacturer’s guidelines. Regular checks for leaks, contamination, and oil level are also important to ensure the gear system remains in good working condition.

Applications of Differentials and Axles (gear oil)

Automotive Transmissions: Both manual and automatic transmissions use gear oil to ensure smooth shifting and operation.
Differentials: Essential for the proper function of differential gears, which distribute power to the wheels.
Transfer Cases: In 4WD and AWD vehicles, gear oil lubricates the transfer case that directs power to different axles.
Industrial Machinery: Used in various heavy-duty equipment and machinery, providing reliable lubrication under extreme conditions.

Conclusion

Castoil Differentials and Axles (gear oil) is a vital component for the efficient and reliable operation of gear systems in vehicles and machinery. Its unique formulation and properties make it indispensable for protecting gears from wear, heat, and corrosion. Choosing the right type and grade of gear oil, as well as adhering to regular maintenance schedules, is essential for ensuring the longevity and performance of gear systems.
