In double rod-end cylinders, the actuator has a rod extending from both sides of the piston and out both ends of the barrel. The piston rod connects the hydraulic actuator to the machine component doing the work. This connection can be in the form of a machine thread or a mounting attachment. The piston rod is highly ground and polished so as to provide a reliable seal and prevent leakage. Induction hardened: Induction hardened is a form of heat treatment in which a metal part is heated by induction heating. Induction hardening of piston rods in hydraulic cylinders is performed in order to increase the resistance to damage from external impact in applications where there is risk for them. The hardness after this heat treatment is HRC 40 to 45. Specification External Diameter Tolerance: Our chrome plated bars are supplied with tolerance f7, f8, f9 on customers鈥?request. Hard Chrome Plated Thickness: Min. 20Microns (0.0008鈥?, other chrome plated thickness of hydraulic cylinder rod is on customers鈥?requests. The chrome plated round bar should pass the salt spray tested at least 48 hours. Supply Length: Our factory produce chrome plated rod with random length or fixed length up to 16 meters. Production process 1. Inspection of raw material 2. Peeling of round bar 3. Rough turning of outer diameter 4. Induction hardened for the bar 5. Fine turning of outer diameter 6. Grinding 7. Polishing 8. Chrome plating 9. Polishing 10. Inspection and packaging Application: Our piston rods are widely used in hydraulic cylinders, air cylinders and shack absorbers directly. And also they are used in printing and dyeing textile equipments, guide rods for liner motions, pressure die casting machines, injection molding machines and other equipments.
