    Hydraulic cylinder rod is an important part of hydraulic cylinder. we use raw materials of 40CR to produce hydraulic cylinder rod. This is also called hydraulic cylinder piston rod. Wekipedia said, the piston rod is typically a hard chrome-plated piece of cold-rolled steel which attached to the piston and extends from the cylinder through the rod -end head. In double rod-end cylinder, the actuator has a rod extending from both sides of the piston and out both ends of 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 attachement. The piston rod is highly ground and polished so as to provide a reliable seal and prevent leakage. Our producton process of hydraulic cylinder piston rod: 1) raw material of 40CR steel purchasing. 2) cutting according to the length. 3) rod heat treatment.(Tempering steel) HB-215-250 4) Induction hardened steel. HRC 50-62 5) chrome plating 0.03-0.05mm 6)rod finish machining 7) welding the Eye 8) painting the rod head.

    Wikepedia shows : Hydraulic Cylinder is a mechanical actuator that is used to give a unidirectional force through a unidirectional stroke. It has many applications, notable in construction equipment ( engineering vehicles), manufacturing machinery, and civil engineering. Hydraulic Cylinders get their power from pressurized hydraulic fluid, which is typical oil. The Hydraulic Cylinder consists of a cylinder barrel, in which a position connected to a piston rod movers back and forth. The barrel is closed on one end by the cylinder bottom (also called the cap) and the other end by the cylinder head (also called the gland) where the piston rod comes out of the cylinder. The piston has sliding rings and seals. The piston divide the inside of the cylinder into 2 chambers, the bottom chamber (cap end) and the piston rod end chamber (head end).
