Precision Engineered Waved Spring for Hydraulic Seals
Hydraulic sealing systems demand elastic elements with ultra-precise deformation control and uncompromising reliability. Our waved spring (wave spring) is engineered to exceed these critical requirements as a precision-engineered component featuring a metal ring with meticulously formed peaks and valleys.
Key Performance Features
- Exceptional elasticity with tensile strength up to 1,350 MPa
- Superior impact resistance, withstanding 480G dynamic loads
- Consistent load-deflection characteristics (±2% tolerance over 10⁶ cycles)
- Optimized for small-load (5N-250N) and micro-deformation (≤0.02mm) applications
- Maintains stable axial preload for optimal compression of hydraulic seals
- Prevents fluid leakage and maintains system pressure integrity up to 350 bar

Surface Treatments & Manufacturing
Surface treatments are specifically designed to enhance sealing performance:
- Dacromet coating provides 1,000+ hours of salt spray resistance (per ASTM B117) for marine hydraulic applications
- Phosphating improves adhesion between spring and seal material, reducing friction by 30%
Our manufacturing process integrates CNC coiling technology and laser welding for dimensional accuracy (±0.01mm), while FEA simulation (ANSYS) optimizes wave geometry to minimize stress concentration.
Quality Assurance & Testing
- Pressure cycling validation (10⁴ cycles at 350 bar)
- Load retention testing (≤1.5% loss after 10⁶ cycles)
- Material certification (ASTM A228/A313 standards)
Application Benefits: Ideal for hydraulic cylinders, valve assemblies, and industrial power units. Our waved springs ensure long-term sealing integrity, reduce maintenance costs, and enhance system safety in critical hydraulic applications.
