Ceramic Piston Rod For Hydraulic Cylinder Corrosion Wear Resistant

Product Specification

Oem Corrosion-Resistant and Wear-Resistant Ceramic Piston Rod for Hydraulic Cylinder                                                    Premium Quality Hydraulic Cylinders - Quality Assured • Internals: Cylinder barrel adopts GUOYUE EU/US metallurgical standard CD250 structure. Barrel material: 45#, 42CrMo, or 27SiMn. Bore honed to H8 precision with surface roughness Ra<0.4μm. Heads, base, trunnions, and pistons are exclusively made of 45# steel; no cast iron or cast steel components are used. • Buffering: Multiple buffering options including fixed and floating buffer structures to ensure effective deceleration across various pressures and speed ranges.  • Welding: 100% ultrasonic impact treatment applied to all pressure-bearing and load-critical welds. This eliminates weld stress (removal rate ≥90%) and significantly enhances weld fatigue strength. • Sealing: All cylinders exclusively use premium imported seals from Japan NOK, Sweden Trelleborg, Germany Merkel, and GP. No domestic seals are utilized. • Testing & Certification: Factory testing strictly complies with GB/T15622-2005 "Hydraulic Fluid Power - Test Methods for Cylinders" and internal premium standard Q/GAKY014-2023. Includes provision of factory test reports and product qualification certificates. • Warranty: One-year warranty from shipment date. Free repair or replacement provided for defects arising from design or manufacturing within the warranty period.Features •  High Corrosion Resistance: The ceramic coating has stable chemical properties and can withstand corrosive media such as water and air. It has passed the salt spray test in a 5% saline solution. In harsh environments, its service life is 5 to 6 times longer than that of ordinary chrome - plated piston rods.                                                                                                                                                                    •  High Wear Resistance: The bonding strength between the ceramic coating and the substrate exceeds 30MPa, with a surface hardness of over 850HV and low friction coefficient, which extends its service life.  •  Smooth Surface: After precision machining, the surface roughness can be controlled within Ra0.3, significantly reducing friction.  •  Easy Maintenance: Equipped with an integrated stroke detection device, the structure is compact and easy to maintain.  •  Environmentally Friendly: The ceramic spraying technology used is pollution - free, avoiding the environmental pollution problems associated with electroplating processes.                                                                                                                                                      Advantages •  Long Service Life: Under the same conditions, its service life is 3 to 6 times longer than that of chrome - plated parts.  •  Wide Range of Applications: Suitable for hydraulic equipment in fields such as water conservancy, petrochemicals, and aerospace.  •  Stable Performance: Equipped with integrated digital stroke control and precise detection accuracy.
