Piston rod for Link-Belt LS-2700

The piston rod, part number KRA0804, serves as a central element within the hydraulic cylinder assemblies of heavy machinery. Its primary function involves transmitting force generated by hydraulic fluid pressure to the exterior of the cylinder, effectively converting hydraulic energy into controlled linear movement. As the rod extends and retracts, it drives the connected load or implement, enabling critical functions such as lifting, pushing, and excavating in equipment like the Link-Belt LS-2700 excavator.

This component is specifically engineered for fitment within the hydraulic systems of the Link-Belt LS-2700. It is typically utilized in the cylinders that operate the boom, arm, or bucket assemblies, where precise movement and force transmission are required for machine operation. Maintaining the integrity of the piston rod surface is necessary for the proper function of the cylinder seals and the overall efficiency of the hydraulic circuit.

In hydraulic systems, the piston rod acts as the mechanical link between the internal piston and the external load. By moving through the cylinder head seals, the rod must maintain strict dimensional tolerances to prevent fluid bypass and ensure smooth operation throughout the full stroke length of the cylinder.
