FAQ
Q1: What is a cylinder piston rod?
A: The piston rod is usually a precision-machined section of hard chrome-plated cold-worked steel bar that transmits the force generated by the piston to the working machine parts, and is the basic and key component of every hydraulic or pneumatic cylinder.
Q2: What is the principle of the cylinder piston rod?
A: The cylinder piston in the cylinder is subjected to the thrust or pulling force generated by the air pressure, and directly acts on the cylinder piston rod connected with the piston, and then the cylinder piston rod is connected to the load workpiece to move back and forth.
Q3: What is the raw material of your cylinder piston rod?
Answer: Usually, the cylinder piston rod of the cylinder will choose 45# steel as the raw material. If the produced cylinder needs to be used in a special environment, 304 stainless steel can also be used, and we can also customize it for you according to your actual needs.
