Buy HITACHI EX120-5 FINAL DRIVE SEAL 68 X 44 X 12MM | Tonkee®

Dimensions: The Hitachi EX120-5 final drive seal has specific dimensions of 68mm in outer diameter, 44mm in inner diameter, and 12mm in thickness.

These measurements are precisely engineered to fit the requirements of the final drive assembly.

Material Composition: Typically, these seals are made from high-quality materials such as rubber or synthetic elastomers. These materials offer excellent resistance to wear, heat, and various hydraulic fluids, ensuring the longevity and reliability of the seal.

Application: The seal is designed for use in Hitachi EX120-5 excavators. It is positioned within the final drive assembly to prevent the escape of hydraulic fluid and to keep external contaminants, such as dirt and water, from entering the system.

Hydraulic Fluid Retention: One of its primary functions is to retain hydraulic fluid within the final drive assembly. Hydraulic fluid is essential for the operation of various components within the excavator, including the motor and gearbox. A compromised seal can lead to fluid leakage, resulting in reduced efficiency and potential damage to components.

Contaminant Exclusion: The seal acts as a barrier against contaminants like dirt, sand, and water.

If these substances infiltrate the final drive assembly, they can cause premature wear and corrosion, leading to costly repairs and downtime.

Reduced Maintenance Costs: A properly functioning final drive seal reduces the need for frequent maintenance and replacement of internal components. This translates to lower operating costs and increased productivity.

Operational Efficiency: Maintaining a tight seal ensures that the hydraulic system operates efficiently, contributing to the overall performance of the excavator. This can lead to increased productivity on job sites.
