What is Hydraulic Power Rod?
- Hydraulic piston rod / hydraulic power rod (commonly used in industrial applications)
- A high-strength metal rod in a hydraulic cylinder that connects to the piston, extends from the cylinder, and transmits hydraulic pressure and linear motion. It is the core load-bearing component of hydraulic actuators.
Synonyms:
- Hydraulic piston rod: the most standard, "hydraulic piston rod"
- Hydraulic cylinder rod: general, "hydraulic cylinder rod"
- Hydraulic rod: abbreviated, "hydraulic rod"

Structure and Materials:
- Material: High-strength carbon steel/alloy steel, with a hard chrome/nickel plating for wear resistance and leak prevention.
- Function: Converts hydraulic energy into mechanical energy to drive loads (robotic arms, buckets, press slides, etc.).
The most commonly used material for hydraulic cylinder rods is carbon steel. Carbon steel hydraulic cylinder rods. The most commonly used carbon steel for hydraulic cylinder rods is CK45, which is known as C45, C45E, this steel is equal to SAE 1045 steel.

Product Features
I.Precision Manufacturing Process
High-precision grinding ensures small outer diameter tolerances and high straightness.
Excellent surface finish ensures smooth, leak-free sealing.
Precise coaxiality prevents deformation during long-term reciprocating motion.
II. Advantages of Use
Even force distribution in hydraulic transmission provides strong load-bearing capacity and stable load-bearing capacity.
Smooth telescopic operation with low noise and fluid movement.
High pressure resistance allows it to withstand high-pressure hydraulic system working environments.
III. Durability and Compatibility
Fatigue-resistant design ensures long service life due to high-frequency reciprocating motion.
Wear-resistant coating is resistant to peeling, reducing future maintenance and replacement costs. A complete range of specifications is available to adapt to various hydraulic cylinders, construction machinery, mining machinery, and agricultural hydraulic equipment.
Packaging & Delivery
All sells honed tubes and chrome rods, usually shipped by sea. In this way, the shipping packaging of the honed tube and chrome rod should pay attention to rust, moisture and impact resistance.Before shipment, we use anti-rust oil with better salt spray resistance, or choose oil-free anti-rust packaging, such as anti-rust film and anti-rust paper.
The packaging of the chrome rod needs to avoid damage during transportation. Paper tubes and straw ropes are usually used for packaging to ensure the neatness of the piston rod and stored in the warehouse.
After all honed tube and piston rod products are packaged, they are packed into custom wooden boxes and transported to the freight port for loading into containers.


JNM GROUP is a quality-centered company. We implement various quality processes in the process of manufacturing honing tubes and piston rods to ensure that the products delivered to customers are of high quality. Adhering to the tenet of "integrity, gratitude, cooperation", "customer satisfaction, win-win cooperation", through continuous innovation and pragmatic management, our company has formed a stable market foundation and a good industry reputation. Our products are deeply loved by customers in Southeast Asia, the Middle East, Central and South America, Europe and other countries.
