Ultra-High-Pressure Hydraulic Cylinders for Extreme Environments

Product Summary

Our ultra-high-pressure hydraulic cylinders are designed for applications exceeding 63 MPa, including high-pressure water jet cutting machines, artillery recoil systems, material pressure-testing apparatus, and other specialized equipment. Manufactured from high-strength 42CrMo4 alloy steel with thick-walled seamless tubing, these cylinders feature forged valve bodies and advanced sealing to withstand extreme cyclic loads. CE 3.1 certified (EN 10210/10219/10025) with a proven track record in heavy machinery stabilility.

Key Selling Points

  • Pressure Over 63 MPa: Capable of handling the most extreme pressure requirements for specialized machinery.
  • 42CrMo4 Alloy Steel Construction: High tensile strength and fatigue resistance for prolonged service under high stress.
  • Forged Valve Bodies & Thick-Walled Seamless Tube: Enhanced structural integrity and safety margins.
  • Metal-to-Metal & Polyurethane Sealing: Reliable sealing even under ultra-high pressure and harsh environments.
  • Case Study – Heavy Machinery OEM in Vietnam: Supplied a cylinder for a straightening machine that has operated reliably for over 10 years with zero major failures, reducing maintenance costs.
