Description:
A Piston assembly is a device used in hydraulic systems to convert fluid power into mechanical force. It usually consists of a piston, piston rod, cylinder, and a seal. The piston is a cylindrical component that fits tightly within the cylinder bore and is moved by the hydraulic pressure of the fluid. The piston rod is connected to the piston and extends from the cylinder to transfer the force generated by the piston to the external load. The cylinder is a hollow tube that contains the piston and allows it to move back and forth within it.
