The piston mainly branches out the pressure areas inside the cylinder’s barrel located within the hydraulic cylinder, however the back and forth action of the piston system is what generates power. The piston rod is fastened to the main piston using threads, nuts, and bolts and other fastening devices; the piston is structured in such a way that it transfers power in linear motion that is consistent.
Pistons are usually of two resting states. One while piston rests in a retracted position, and the second where the piston rests in an extended position. In other words, when pressure is applied on the end side cap, the cylinder rod will extend and when the pressure is applied at the opposite end the cylinder rod will retract.
