Buy HITACHI ZAXIS ZX130 HYDRAULIC PUMP SERVO PISTON (ITEM 42 OEM HI 4428917) | Tonkee®

The hydraulic pump servo piston is a vital part of the hydraulic system in the Hitachi ZAXIS ZX130 excavator.

This system is responsible for powering various hydraulic functions, such as the boom, arm, and bucket movements, as well as controlling the machine's overall hydraulic performance. The servo piston plays a crucial role in regulating the flow and pressure of hydraulic fluid within the system, ensuring smooth and precise operation of the excavator.

One of the key specifications of the HI 4428917 servo piston is its material composition. Typically, these pistons are made from high-quality materials such as hardened steel or other alloys to withstand the high pressures and forces encountered in hydraulic systems. This robust construction ensures the longevity and reliability of the piston in demanding construction environments.

The servo piston's dimensions are also crucial. It is designed to fit precisely within the hydraulic pump, creating a tight seal to prevent fluid leakage and maintain hydraulic efficiency. These dimensions are engineered to meet strict tolerances to ensure proper function and compatibility with the ZAXIS ZX130 excavator.

Another important specification is the piston's surface finish. The piston's surface must be precisely machined and polished to minimize friction and wear. This smooth surface ensures that the piston moves freely within the hydraulic pump, contributing to the overall efficiency and performance of the excavator.

The HI 4428917 servo piston is engineered to operate under high pressure conditions.

Hydraulic systems in excavators like the ZAXIS ZX130 can generate substantial pressure to perform heavy-duty tasks. Therefore, the servo piston must be designed to handle these pressures without failure, maintaining the machine's productivity and safety.

Sealing is a critical aspect of any hydraulic component, and the servo piston is no exception. Proper seals are essential to prevent hydraulic fluid from escaping and contaminants from entering the system. The HI 4428917 piston is equipped with high-quality seals that are resistant to wear and provide an effective barrier against fluid leakage, ensuring the hydraulic system's integrity.

Moreover, the HI 4428917 servo piston is designed for easy installation and replacement. In the event of maintenance or repairs, having components that can be quickly and efficiently swapped out is crucial to minimizing downtime on the job site. This design feature contributes to the overall cost-effectiveness of the ZAXIS ZX130 excavator.
