The piston rod is a fundamental and critical component of every hydraulic or pneumatic cylinder. The piston rod typically is a precision machined length of hard chrome plated cold finished steel bar which transmits the force created by the piston to the machine component doing the work. Although a vital part of the hydraulic cylinder, the rod is often taken for granted — until a problem arises.

The hydraulic cylinder piston rod is a connecting part that supports the piston to do work, as well as a moving part with frequent movement and high technical requirements. The quality of its processing directly affects the life and reliability of the hydraulic cylinder, which has high processing requirements and strict requirements on coaxiality and wear resistance. Today let’s learn more about the manufacturing process of it.
