What are the usages of cylinder rod?

Usage of the cylinder rods and its importance in hydraulic cylinders

Cylinder rods play a crucial role in the efficient functioning of hydraulic and pneumatic systems. As a result, the quality of a hydraulic cylinder is heavily influenced by the quality of its cylinder rod. Cylinder rods must adhere to high processing standards to ensure they meet the technical requirements of these systems.

The cylinder piston rod is an essential component that supports the work of the piston and is primarily used in oil cylinders and other motion execution parts. This moving part experiences frequent movements and requires high levels of technical expertise. The cylinder piston rod is usually made of chrome plated bar or chrome plated hollow rod.

When considering hydraulic cylinders, it is essential to note that they are composed of various parts, including the hydraulic cylinder barrel, piston rod, piston, and end cover. The processing quality of these components is critical, with the cylinder rod playing a particularly important role. The cylinder rod’s processing requirements are exacting, and its surface roughness must meet a strict requirement of max Ra0.4. The cylinder rod must also exhibit high levels of coaxiality and wear resistance to guarantee reliable and long-lasting operation.

Another critical component in hydraulic cylinders is the cylinder piston rod packing ring, which is responsible for sealing the gap between the cylinder seat and the piston rod. This packing ring has three gaps: axial clearance, which allows the ring to move freely, radial clearance, which prevents deformation or damage caused by piston rod sinking, and a gap between the packing ring and the cylinder wall. By preventing the leakage of fluid from the cylinder, the packing ring ensures that the hydraulic system operates efficiently and effectively.

In conclusion, hydraulic and pneumatic systems rely heavily on the quality of cylinder rods, which must adhere to high processing standards to guarantee reliable and long-lasting operation. Cylinder piston rods and packing rings are also essential components that play vital roles in the overall functioning of hydraulic systems. By understanding the technical requirements of these components, manufacturers can design and produce hydraulic systems that meet the demands of various applications.

The cylinder piston rod is the connecting part that supports the work of the piston. Most of them are used in the oil cylinder and the cylinder motion execution part. It is a moving part with frequent movements and high technical requirements. 

Taking the hydraulic cylinder as an example, it is composed of: hydraulic cylinder tube (cylinder barrel), piston rod (cylinder rod), piston, and end cover. The quality of its processing directly affects the life and reliability of the entire product. The cylinder rod has high processing requirements, and its surface roughness is required to be Ra0.4 ~ 0.8um, and the requirements for coaxiality and wear resistance are strict.

The primary purpose of the packing ring on the cylinder piston rod is to create a seal between the cylinder seat and the piston rod, effectively preventing any leakage from the cylinder piston rod. Typically, there are three gaps present in the piston rod packing: axial clearance, which allows the packing ring to move freely to enable normal operation of the piston rod; and radial clearance, which prevents the compression of the packing ring due to sinking of the piston rod, thereby avoiding any potential deformation or damage.
