Core Advantages
High-Quality Material Selection:
Crafted from high-grade steels, including CK20, CK45, and 42CrMo for the cylinder body and piston rod, the product boasts excellent mechanical properties to meet the demands of heavy-duty engineering operations. The cylinder body achieves a hardness of HRC45-55, while the piston rod undergoes quenching, tempering, and hard chrome plating with a chrome layer thickness precisely controlled between 30～50 microns and a surface tolerance of Ra 0.2～0.4, delivering superior wear resistance and corrosion resistance to extend service life effectively. The sealing system offers multiple options: high-quality Chinese-manufactured seals, Hallite, or Merkel seals. Combined with a 160 bar working pressure design (engineering-grade cylinder compatible with 16-25 MPa pressure scenarios), it ensures efficient and leak-free hydraulic transmission.

Authoritative Certifications:

The product has obtained dual international certifications:

ISO 9001:2008 and CE, adhering to strict quality management systems throughout the production process. Each batch comes with a mechanical test report and outgoing inspection video. From raw material warehousing to finished product delivery, it undergoes 11 core processes, including rough machining, welding, polishing, and pressure testing, ensuring every hydraulic cylinder meets standard specifications. The supplier's 100% positive review rate is a testament to its consistent quality.
