Hengshan Technology has long been deeply engaged in the precision manufacturing of piston rods. , has accumulated mature core processes in forging and precision turning‑milling. Focused on the R&D and production of double-threaded piston rods compatible with the entire range of passenger and commercial vehicle models. This article will focus on two core shock-absorbing piston rod products: 20*390 Shock Absorber Piston Rod with Square Hole and 18*361 Milling Double-Sided Shock Absorber Piston Rod , comprehensively showcasing the product’s manufacturing advantages and application value.
20*390 Shock Absorber Piston Rod with Square Hole
This piston rod adopts High-strength alloy material Forged and formed, then meticulously finished through multiple precision machining processes, the rod body boasts a smooth, polished surface with exceptional wear resistance, featuring… Exceptional resistance to bending and fatigue. , capable of long-term adaptation to complex vehicle driving conditions, with stability maximized. The product’s two ends Adopts an integrally molded standard threaded structure. It features high precision and tight engagement, enabling accurate assembly and secure locking of the shock absorber’s upper and lower ends, thereby eliminating any risk of loosening during installation.
The shaft features a custom‑stamped square‑hole differential structural design that integrates three core functions: positioning and limiting, hydraulic flow guidance, and anti‑rotation fixation. , it can precisely match the positioning requirements of core components such as the shock absorber’s internal valve body and oil seals, offering exceptional assembly compatibility. This product Widely compatible with hydraulic and pneumatic shock absorber assemblies for passenger cars and commercial vehicles. It effectively stabilizes shock‑absorbing damping, cushions road bumps and vibrations, enhances the body’s structural rigidity, and significantly improves the overall operational stability and service life of the shock absorbers.
18*361 Milling Double-Sided Shock Absorber Piston Rod
This product is crafted from high-strength, premium-grade steel and manufactured through… Precision turning and milling processes for shaping and forming. , with a highly polished shaft that is wear-resistant and durable, featuring Excellent tensile strength and fatigue resistance , capable of withstanding long-term, high-frequency shock-absorbing operations and resistant to deformation and damage. Product Both ends are machined with precision‑turned standard threads. The threads are well‑formed and the tolerances are precise, ensuring perfect compatibility with the assembly and locking requirements of various shock absorber assemblies, while offering easy installation and excellent fit.
The shaft is manufactured using an integrated milling process on a milling machine, producing bilateral flat surfaces. , featuring high forming accuracy and excellent structural symmetry, it seamlessly integrates critical functions such as anti-rotation limiters, assembly locating features, and hydraulic guidance, thereby fundamentally preventing issues like equipment installation misalignment, operational looseness, and positioning deviations. Product Compatible with all hydraulic shock absorber models for passenger cars and commercial vehicles. It can smoothly transmit shock‑absorbing damping forces, stabilize the overall suspension structure, significantly enhance vehicle ride smoothness and occupant safety, and effectively extend the service life of the shock absorber assembly.
Chongfang Kong 、 Double-sided milling Two differentiated structural designs precisely accommodate shock-absorbing devices for vehicles of various types and specifications. Comprehensively covers the full range of supporting needs for both passenger and commercial vehicles. 。 Hengshan Technology We consistently uphold precision manufacturing standards, leveraging mature machining processes and a rigorous quality-control system.
