The Hydraulic piston rod is a crucial component engineered to improve the functionality and reliability of cranes. Crafted from premium materials and precision-engineered, this piston rod ensures smooth and efficient operations, enhancing the overall performance and safety of cranes used in various industries, including construction, shipping, and heavy industrial sectors.
Dimensions, Diameters:
The Hydraulic piston rod has a wide range of diameters, which can range from Phi 18 to Phi 250mm according to different application needs.
Length: The length of the piston rod is usually between 15cm and 50cm, but longer lengths can be customized according to specific needs. For example, in some applications, the length of the piston rod may reach 3000mm or 6000mm.
Hydraulic rod Material:
The material selection of piston rod is various, including carbon Steel (such as Steel grade 45#, DIN CK45/JIS 45C), low alloy steel, aluminum alloy, stainless steel and titanium alloy.
Hydraulic piston rod,The choice of these materials depends on factors such as the strength, toughness, wear resistance, heat resistance and corrosion resistance required for the piston rod.
Hydraulic piston rod Mechanical properties
Yield strength: the piston rod needs to have a certain yield strength to ensure that it is not prone to plastic deformation when subjected to external force. Common yield
strength requirements are 320Mpa or greater.
Hydraulic piston rod Tensile strength
Tensile strength is a measure of a material’s maximum ability to resist tensile damage. The tensile strength of the piston rod is usually required to be ≥580Mpa.
Hydraulic piston rod Elongation
The piston rod material needs to have a certain elongation to ensure that a certain degree of plastic deformation can occur without breaking immediately when subjected to tensile
forces. Common elongation requirements are ≥15%.
Hydraulic piston rod Surface treatment:
The surface treatment of the piston rod is essential to improve its wear resistance and corrosion resistance. Common surface treatment methods include Hard chrome
plated and medium and high frequency Induction hardening. Hard chrome plating can improve the hardness and wear resistance of the piston rod surface, while induction hardening at medium and high frequency can improve its internal structure and mechanical properties.
Tolerance and surface roughness:
Tolerance: The tolerance of the piston rod is usually controlled according to the ISO f7 standard to ensure that its dimensional accuracy meets the requirements of the application.
Surface Roughness: The surface roughness of the piston rod has an important effect on the friction and wear between it and the seal. Common surface roughness requirements are Ra0.2um(max).
Straightness and quenching hardness:
Straightness: The straightness of the piston rod is an important indicator of its axial deviation. The straightness of the piston rod is usually required to be within 0.2/1000mm.
Induction hardness: For the piston rod that is quenched by medium and high frequency induction, its quenching hardness is usually between 50-55HRC.
Corrosion resistance:
Salt spray testing (Corrosion resistance) : The corrosion resistance of the piston rod has been assessed through salt spray testing. Min120hours NSS Rating 9 Test acc.To ISO9227 and ISO
In summary, the technical parameters of the piston rod cover many aspects such as size, material, mechanical properties, surface treatment, tolerance and surface roughness, straightness and
quenching hardness, and corrosion resistance. The selection and determination of these parameters need to be comprehensively considered according to the specific application requirements and working environment.
