Hot sale HITACHI EX60 75 UH SERIES TRAVEL DEVICE FINAL DRIVE D RING BRAKE O-RING SEAL (120 X 109.50 X 6MM) | Tonkee®

The D Ring Brake O-Ring Seal is a critical component within the travel device or final drive assembly of an excavator.

Final drives are essential for the mobility of excavators, allowing them to move forward and backward by propelling the tracks or wheels. The O-ring seal, with its specific dimensions, is designed to prevent the leakage of hydraulic fluid, maintain lubrication, and ensure the proper functioning of the brake system within the travel device.

Dimensions:
The seal's dimensions are precisely specified as 120 x 109.50 x 6mm. These measurements are crucial to ensure a proper fit within the travel device assembly, preventing any gaps or misalignment that could lead to hydraulic fluid leaks or diminished braking performance.

Material Composition:
The choice of material for this O-ring seal is paramount. It must withstand the harsh conditions and stresses encountered in heavy machinery applications. Typically, these seals are made from high-quality rubber or synthetic elastomers. These materials possess excellent resistance to hydraulic fluids, oils, and extreme temperatures, ensuring the longevity and durability of the seal.

Functionality:

Hydraulic Fluid Containment: One of the primary functions of the D Ring Brake O-Ring Seal is to contain hydraulic fluid within the travel device.

As the excavator's tracks or wheels move, the hydraulic system engages, and this seal prevents any leakage, ensuring a consistent supply of hydraulic power to the travel device.

Lubrication Maintenance: Proper lubrication is vital for the longevity of the final drive components. The seal helps maintain the lubricating oil or grease within the assembly, reducing friction and wear on critical parts, thereby extending their lifespan.

Brake System Integrity: The seal also plays a critical role in the brake system of the travel device. It ensures that the brake components remain lubricated and that contaminants are kept out. This is essential for the safety and control of the excavator, allowing it to stop or slow down when necessary.

Environmental Protection: Heavy machinery often operates in challenging environments, including construction sites with dust, dirt, and debris. The O-ring seal helps protect the internal components of the travel device from these external elements, preventing damage and maintaining operational efficiency.
