In hydraulic systems, seals demand 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. Designed to generate stable axial preload across dynamic operating conditions, it ensures consistent contact pressure between sealing surfaces—effectively eliminating micro-leakages even in high-pressure hydraulic circuits (up to 350 bar). 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. Our material selection is optimized for hydraulic environments: 50CrVA (chrome-vanadium spring steel) offers superior tensile strength (>1,800 MPa) and fatigue resistance (over 10^6 cycles at 70% of yield strength), while SUS316 (marine-grade stainless steel) provides exceptional corrosion resistance in aggressive media such as mineral oils, water-glycol mixtures, and saltwater environments.
To further enhance durability, we apply advanced surface treatments tailored to operating conditions: phosphating (8-12 μm thickness) creates a porous layer that improves lubricant retention and wear resistance; dacromet coating (5-8 μm) delivers 1,000+ hours of salt spray resistance per ASTM B117; and black oxide finishing provides a 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 (via光谱仪), 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.
