Lower piston plate for Kobelco machinery

The lower piston plate, identified by part number A21130-01, serves as a critical internal component within hydraulic systems found in various Kobelco machines. This plate is engineered to manage the movement of pistons, playing a fundamental role in the transmission of force and the operational control of the assembly. Its design ensures that the system maintains necessary operating tolerances and structural integrity during use.

This component is specifically designed for integration into Kobelco heavy equipment, such as excavators and cranes. The plate functions within the core of hydraulic units, including axial or radial piston pumps, where it assists in the conversion between mechanical and hydraulic energy. By guiding the pistons, the plate ensures the precise interaction required for the system to function effectively.

In hydraulic systems, a piston plate acts as a guide and support surface for the piston assembly. It is essential for maintaining the alignment and movement required to generate hydraulic pressure or convert fluid flow into mechanical work. Proper function of this plate is necessary to support the volumetric efficiency of the pump or motor, ensuring that the machine maintains consistent power and responsiveness during operation.
