Product Description
In hydraulic systems, seals require elastic components that deliver minimal deformation under cyclic pressure and uncompromising reliability to prevent catastrophic fluid leakage. SUNZO Disc Spring is meticulously engineered to meet these critical requirements, serving as a high-performance solution for hydraulic seal applications.
The spring's unique conical geometry provides exceptional stiffness-to-size ratio, enabling it to absorb shock loads and vibration without permanent deformation—a critical advantage in mobile hydraulic equipment and industrial machinery.
Featuring dynamically adjustable stiffness characteristics and broad non-linear load-deflection curves, SUNZO Disc Spring can be configured in series, parallel, or nested stacks to precisely match the pressure profiles of diverse hydraulic seal systems—from low-pressure actuators to high-pressure hydraulic cylinders.
• 50CrVA (chrome-vanadium spring steel): Superior tensile strength (>1,800 MPa) and fatigue resistance (over 10^6 cycles at 70% of yield strength)
• SUS316 (marine-grade stainless steel): Exceptional corrosion resistance in aggressive media including mineral oils, water-glycol mixtures, and saltwater environments
- Phosphating (8-12 μm thickness): Creates porous layer for improved lubricant retention and wear resistance
- Dacromet Coating (5-8 μm): Delivers 1,000+ hours salt spray resistance per ASTM B117
- Black Oxide Finishing: Provides low-friction surface ideal for dynamic sealing applications
Each spring undergoes rigorous quality testing including load-deflection curve verification (per ISO 16148), material composition analysis, and fatigue life assessment using servo-hydraulic test rigs.
Backed by ISO 9001:2015 certification and full traceability from raw material to finished product, SUNZO Disc Spring ensures long-term reliability in critical hydraulic seal applications such as valve manifolds, piston rods, and hydraulic power units.
