High-Pressure Hydraulic Cylinders for Demanding Applications

Product Summary

Our high-pressure hydraulic cylinders are engineered for heavy-duty applications requiring reliable linear motion under pressures from 31.5 to 63 MPa. Manufactured from high-quality seamless steel tubes (ST52, C45, 42CrMo4) and certified to CE 3.1 (EN 10210/10219/10025), these cylinders deliver exceptional dimensional stability, low friction, and long service life. Customizable in OD (20-800 mm), wall thickness (3-50 mm), and length (6-12 m), they are ideal for hydraulic excavators, four-column presses, marine steering gear, and more.

Key Selling Points

  • Pressure Range 31.5-63 MPa: Suitable for the most demanding heavy machinery applications.
  • Metal-to-Metal Sealing: Combined with high-performance polyurethane seals for leak-free operation and extended durability.
  • ISO H8/H9 Bore Tolerance & Ra ≤ 0.4 μm Roughness: Ensures consistent performance and minimal friction.
  • CE 3.1 Certified: Complies with EN 10210, EN 10219, and EN10025 standards for European market requirements.
  • Overpressure Protection: Built-in safety devices safeguard against overload conditions.
  • Customizable Options: Choose from various materials, port configurations, and mounting styles to match your system.

Models and Options

Available in piston, plunger, telescopic (multi-stage), and rotary (oscillating) configurations. Custom port sizes, rod diameters, and mounting brackets can be produced per your drawing or application requirements.

Materials and Structure

Standard materials include ST52, S355, E355, C45, SAE1045, and 42CrMo4. The cylinder barrel is made from thick-walled seamless steel tube (hot-rolled or cold-drawn). The piston rod is hardened and chrome-plated for wear resistance. Sealing system combines metal-to-metal contact with high-performance polyurethane seals for low leakage.

Applications

  • Engineering machinery (excavators, crushers)
  • Four-column hydraulic presses
  • Marine systems (steering gear, anchor winches)
  • Automobile industry manufacturing equipment
  • Factory automation and material handling
