OEM HITACHI EX ZX120 TRACK ADJUSTER O-RING 62 X 50 X 5.5 MM (OEM HI 4360347) | Tonkee®

The Hitachi EX ZX120 track adjuster O-ring measures 62 millimeters in outer diameter (OD), 50 millimeters in inner diameter (ID), and has a thickness of 5.5 millimeters.

These precise measurements are crucial for a snug fit within the track adjuster assembly, ensuring it can effectively seal and prevent hydraulic fluid leakage.

Material Composition:

This O-ring is typically made from high-quality rubber or elastomeric materials that are known for their resilience and resistance to hydraulic fluids, high temperatures, and wear and tear. The specific rubber compound used in the manufacture of this O-ring is engineered to withstand the harsh operating conditions that excavators like the Hitachi EX ZX120 are exposed to. This ensures its longevity and reliability in demanding construction environments.

Function and Importance:

The track adjuster assembly in an excavator is responsible for maintaining the proper tension of the tracks. This tension is crucial for the excavator's stability, maneuverability, and overall performance. The O-ring, with its sealing properties, is a critical component within the adjuster assembly.

When the hydraulic system within the excavator is activated to adjust the track tension, the O-ring prevents hydraulic fluid from escaping and maintains a consistent pressure.

This pressure is what allows the tracks to be adjusted to the correct tension, ensuring they stay in alignment and function optimally.

A well-functioning track adjuster assembly with a properly sealed O-ring contributes to:

Stability: Properly tensioned tracks ensure the excavator maintains stability, reducing the risk of tipping or accidents during operation.

Maneuverability: Correctly tensioned tracks allow the operator to easily control the excavator's movements, enhancing precision when digging or moving materials.

Durability: Maintaining the right track tension reduces wear and tear on the undercarriage components, extending their lifespan and reducing maintenance costs.

Efficiency: An excavator with well-maintained tracks operates more efficiently, completing tasks faster and with less fuel consumption.

Safety: A secure track tension prevents sudden track dislocation, reducing the likelihood of accidents and injuries on the construction site.
