Shop HITACHI EX100 120-ALL MODELS BUCKET LINKAGE O-RING (125 X 105 X 10MM) | Tonkee®

The O-ring, measuring 125 x 105 x 10mm, is a specialized sealing component designed to fit precisely within the bucket linkage of the Hitachi EX100 and EX120 excavators.

Its dimensions are critical to its function, ensuring a secure and watertight seal between various components of the linkage system. The O-ring's outer diameter of 125mm, inner diameter of 105mm, and thickness of 10mm are engineered to match the specific requirements of these excavator models.

Material composition is a crucial consideration for O-rings used in heavy machinery like excavators. Typically, these O-rings are made from high-quality rubber or elastomer materials, known for their excellent resistance to wear, tear, and extreme environmental conditions. This ensures the longevity and reliability of the O-ring, even when subjected to the rigorous demands of excavation work.

The primary function of the O-ring in the bucket linkage system of the Hitachi EX100 and EX120 excavators is to provide a secure and leak-proof seal. When properly installed, it prevents hydraulic fluid from leaking out and contaminants from entering critical components of the linkage system. This sealing action is essential for maintaining the efficiency and performance of the excavator during operation.

During the operation of the excavator, hydraulic fluid is used to control the movement of the bucket and arm. Any leakage in the hydraulic system can result in reduced performance and potential damage to the machine. The O-ring, with its precise dimensions and high-quality material, acts as a barrier against such leaks, ensuring that the hydraulic system functions optimally.

Moreover, the O-ring also contributes to the overall safety of the excavator and the operator.

A properly sealed linkage system prevents unexpected movements or failures that could pose risks to those working with or around the machine. It helps maintain control over the bucket's movement, enhancing the operator's ability to perform precise digging and lifting tasks.

In addition to its sealing function, the O-ring is designed to withstand the rigors of heavy-duty excavation work. It can endure extreme temperatures, pressures, and exposure to various chemicals and contaminants commonly encountered in construction and excavation sites. This resilience ensures that the O-ring continues to perform effectively under challenging conditions, minimizing downtime and maintenance costs.
