Shop HITACHI EX100 120-1 EX135 FH130 TRAVEL DEVICE FINAL DRIVE OIL SEAL (PAIR) | Tonkee®

The travel device final drive oil seal (pair) for the Hitachi EX100, EX120-1, EX135, and FH130 excavators is a critical component that contributes to the overall performance and longevity of these machines.

These excavators are widely used in construction, mining, and various earthmoving applications, making the reliability of their components essential for productivity and safety.

Constructed with precision and durability in mind, this oil seal is designed to fit snugly within the final drive assembly, creating a tight barrier between the internal components and the external environment. Its primary function is to prevent the leakage of hydraulic fluid, also known as final drive oil, from the drive assembly. This hydraulic fluid is responsible for powering the tracks or wheels of the excavator, allowing it to move efficiently.

Additionally, the oil seal acts as a defense against external contaminants such as dirt, sand, and water. These contaminants, if allowed to enter the final drive assembly, can lead to premature wear and damage to critical components, resulting in costly repairs and downtime.

The Hitachi EX100 120-1 EX135 FH130 travel device final drive oil seal (pair) is manufactured to meet stringent quality standards.

It is typically made from high-quality rubber or elastomeric materials known for their resistance to hydraulic fluids and environmental factors. This ensures that the seal remains effective over an extended period.

One of the key features of this oil seal is its dual configuration, which is why it is referred to as a "pair." The dual setup consists of two oil seals working in tandem within the final drive assembly. This redundancy enhances the seal's effectiveness in preventing oil leaks and the ingress of contaminants. Even if one seal were to fail due to wear or damage, the second seal would continue to provide protection, reducing the risk of catastrophic failures and associated downtime.

Maintenance of the travel device final drive oil seal (pair) is crucial to ensure the excavator's continued reliability. Regular inspections should be performed to check for signs of wear, damage, or leakage. Any visible issues should be addressed promptly by replacing the damaged seal with a new one.
