We are recognized as a benchmark supplier of ultra-stable hydraulic cylinders for global construction machinery, mining equipment, special vehicles and large-scale infrastructure projects.
01 · BRAND HERITAGE
Thirty Years of Dedication, Forging an Industry Legend
Since its establishment, Zhenqiang Machinery has always focused on the customization, R&D, production and precision forging of various high-end hydraulic cylinders. Over 30 years of industry evolution, we have accumulated millions of sets of real-world equipment data, a complete set of mature production processes and an exceptionally rigorous quality-control system.
For 30 years, we have focused on one thing: making only high-quality, ultra-durable hydraulic cylinders with zero-repair-level reliability.
Through decades of continuous technical accumulation, Zhenqiang Machinery has completely overcome common industry pain points such as oil leakage, deformation, insufficient load capacity and short service life, becoming the preferred supplier of ultra-high-strength, ultra-long-life and ultra-stable hydraulic power components for customers in China and overseas.

02 · FACTORY STRENGTH
Full-Chain Intelligent Manufacturing & Top-Tier Production Scale
Zhenqiang Machinery operates a large, modern and standardized hydraulic cylinder production base. We integrate independent R&D, precision forging, CNC finishing, high-pressure testing, dust-free assembly, fully automated inspection and export customization, achieving 100% independently controlled full-chain production from incoming raw materials to finished-product export.
The factory is equipped with a complete range of imported high-end CNC machining centers, fully automatic deep-hole boring machines, precision grinding machines, high-pressure endurance test benches and non-destructive testing equipment. Every hydraulic cylinder undergoes:
Ultra-High-Pressure Limit Testing
Repeated Telescopic Fatigue Testing
Seal Leakage-Prevention Durability Testing
Heavy-Load Deformation Resistance Testing
Extreme High- and Low-Temperature Simulation Testing
We insist that every cylinder is fully inspected before leaving the factory and delivered with zero defects, completely eliminating common industry problems such as defective products, rework, oil leakage and pressure loss. Product stability, durability and safety factors far exceed general industry standards.
