High-precision hydraulic piston manufactured from alloy steel, specifically engineered for axial piston pump and motor systems.
Alloy steel material provides exceptional tensile strength and wear resistance, ensuring efficient and reliable operation of hydraulic transmission systems.
The piston serves as the core moving component in axial piston pumps and motors, installed within the cylinder block and achieving reciprocating motion through coordination with swash plates or bent axes. Manufactured from alloy steel, it offers superior strength and toughness. Its precision-machined external surface forms an oil film lubrication pair with the cylinder bore, ensuring efficient hydraulic transmission. The piston's design features include wear-resistant surfaces treated with carburizing and quenching, precision-ground cylindricity, and specially designed oil passage structures. When paired with piston shoes and retaining rings, extremely high fitting accuracy and concentricity are required to ensure reliable operation of the entire system.
We selected alloy steel as the piston material primarily considering its high tensile strength and excellent surface hardening capabilities. After carburizing and quenching treatment, this alloy steel exhibits outstanding fatigue strength and wear resistance, capable of withstanding high-frequency reciprocating motion and pressure in hydraulic systems. The addition of alloying elements enhances the material's toughness, corrosion resistance, and wear resistance, while precise carbon content control ensures a balance between machinability and hardening performance. Compared to other engineering steels, alloy steel demonstrates superior comprehensive performance under high-load conditions. To enhance durability, products undergo carburizing and quenching treatment to increase surface hardness and wear resistance. Finally, we perform precision grinding to ensure cylindricity accuracy and conduct rigorous dimensional inspection to meet high-precision hydraulic system requirements.
