Product Description


                          Custom Precision Hydraulic Cylinder Piston Rod for Auto



Piston rods are steel rods made of C1045/CK45 or 42CrMo/4140 material Ground and Hard Chrome plated surface.The rods undergo rigorous processes like pilling, straightening, hardening, grinding, polishing, hard chrome plating and finishing under the supervision of experienced engineers.

Hard Chrome Plated Piston Rods are widely used in hydraulic and pneumatic cylinder, printing machinery, textile machinery, engineering machinery, wood working machinery, etc. Our products are highly appreciated by our clients for their features like corrosion resistance, robust construction, elevated durability, high tensile strength and the mirror-like surface.

Cylinder head
The main function of the head is to enclose the pressure chamber from the other end. The head contains an integrated rod sealing arrangement or the option to accept a seal gland. The head is connected to the body by means of threading, bolts, or tie rod.

Piston rod

The piston rod is typically a hard chrome-plated piece of cold-rolled steel that attaches to the piston and extends from the cylinder through the rod-end head. 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

Cylinder base or cap
The main function of the cap is to enclose the pressure chamber at 1 end. The cap is connected to the body by means of welding, threading, bolts, or tie rod. Caps also perform as cylinder mounting components [cap flange, cap trunnion, cap clevis]. Capsize is determined based on the bending stress.
