Detailed Description

The 3103242 ROD PISTON HITACHI is engineered with high-precision tolerances to meet the tough demands of modern excavating environments. As part of the hydraulic cylinder assembly, this piston rod transmits hydraulic force from the piston to the working end of the excavator. Constructed from high-grade alloy steel and treated with a chrome-plated surface, this component is built to resist wear, corrosion, and pitting that typically arise from heavy hydraulic loads and high-pressure fluid operation.

Its robust cylindrical body ensures stability and durability even in high-vibration, high-pressure working conditions. The chrome finish reduces friction and minimizes the wear rate against seals and cylinder walls, preserving the hydraulic integrity of the system over time. Whether operating in cold or hot climates, or across abrasive terrain, the 3103242 ROD PISTON HITACHI maintains consistent performance.

Role in Excavating Systems

Within the hydraulic cylinder, the piston rod is the load-bearing member that connects the piston to the actuator mechanism, often a boom or arm. The 3103242 ROD PISTON HITACHI ensures that the hydraulic pressure generated inside the cylinder is effectively transmitted, with minimal energy loss. It plays a key role in determining the extension and retraction force of the cylinder, which
