Product Description
OEM Shock Absorber Piston Rod — Engineered for Long-Term Reliability

As a critical component within any shock absorber assembly, the piston rod must withstand continuous cyclic loading, resist surface wear, and maintain precise dimensional tolerances over millions of strokes. Our OEM Shock Absorber Piston Rod is manufactured with induction hardened surfaces and hard chrome plating to deliver the durability, straightness, and corrosion resistance that automotive and industrial equipment manufacturers demand for consistent, maintenance-free performance.

Key Performance Advantages

Extended Service Life: Induction hardened surface layer combined with 10–25 μm hard chrome plating provides superior wear resistance, dramatically reducing the risk of premature rod scoring or seal failure in high-cycle applications.

Consistent Dimensional Stability: Straightness controlled to ≤ 0.2 mm per 1000 mm and surface roughness below Ra 0.2 μm ensure smooth, chatter-free operation and a perfect seal interface — minimizing fluid leakage and warranty returns.

Corrosion Protection: Hard chrome finish creates an effective barrier against moisture, road salt, and chemical exposure, making these rods suitable for both on-road and off-road vehicle platforms.

OEM-Grade Quality Assurance: IATF 16949:2016 certified production with 100% inspection at final stage. Each batch is traceable to raw material heat number, giving you full confidence in supply chain integrity.

Frequently Asked Questions

Q1: Are you a manufacturer or a trading company?

We are a direct manufacturer with more than 15 years of experience in CNC precision machining. You are welcome to visit our factory in Ningbo, China.

Q2: What types of components can you supply besides piston rods?

Our production covers piston rods, oil seals, rubber parts, pistons, stamping parts, and powder metallurgy components for shock absorber and hydraulic cylinder applications.

Q3: What is your typical production lead time?

5 working days for in-stock items; 15–45 days for mass production orders, depending on quantity and complexity.

Q4: What payment terms do you accept?

We accept T/T, L/C at sight, and Western Union. Standard terms are 30% deposit with order confirmation and 70% balance before shipment. For established partnerships we can discuss open account terms.

Q5: Can you customize piston rods to our drawings and specifications?

Absolutely. We work from customer-supplied drawings in SolidWorks, Pro/E, AutoCAD, UG, or PDF format. Our engineering team can also assist with design-for-manufacturability feedback to optimize your design for cost and production efficiency.

Q6: How do you ensure consistent quality across large production batches?

Every batch undergoes 100% final inspection with documented dimensional reports. Our IATF 16949:2016 certified quality system includes in-process SPC checks, material heat traceability, and retained samples from each lot. We use Mitutoyo inspection instruments calibrated to international standards.

Q7: What is the minimum order quantity?

Our standard MOQ is 100 sets per order. For new project development or prototype validation, we can accommodate smaller trial quantities — please contact our sales team to discuss your specific requirements.
