Product Description
Detailed Specifications & Features
Premium Nested Wave Spring Solutions: High-Force Elastic Technology by Jiangsu Sunzo
In high-end mechanical engineering and precision component design, managing massive loads within confined spaces presents significant challenges. Traditional wave springs or standard coil springs often reach their limits when applications demand immense forces within tight, small diameters. Jiangsu Sunzo Spring Elasticity Technology Co., Ltd. (SUNZO) delivers the ideal solution: premium Nested Wave Springs.
Core Technical Advantages
Multiplied Load Capacity: Our nested wave springs multiply force proportional to the number of parallel turns, achieving forces equivalent to heavy-duty Belleville washers with more predictable flat-wire profiles.
Elimination of Assembly Issues: The single, continuous strand design ensures perfect alignment, eliminating internal shifting, reducing friction wear, and guaranteeing consistent force-deflection profiles.
Smooth Linear Force: Advanced edge-coiling technology ensures even load distribution across nested layers, enabling smooth, linear deflection throughout the working stroke.
Structural Stability: Every spring undergoes intensive mechanical pre-setting to remove initial material stresses, maintaining precise free height and resisting relaxation after millions of high-load cycles.
Advanced Material Selection
- Carbon Spring Steels (SAE 1070-1090 / 65Mn): High tensile strength and cost-effectiveness for non-corrosive environments
- Austenitic Stainless Steels (SUS 302, 304, 316): Robust rust and acid resistance, with SUS 316 ideal for marine and chemical environments
- Precipitation-Hardening Stainless Steel (17-7PH): Exceptional fatigue resistance and structural stability up to 315°C (600°F)
- Nickel-Chromium Superalloys (Inconel X-750 / 718): Extreme high-temperature resistance (up to 700°C) and chemical media protection

Design Integration: Our engineering division provides advanced Finite Element Analysis (FEA) modeling to visualize wave nesting, inter-turn friction mechanics, and stress-strain distributions. We support rapid prototyping with no minimum order quantity (No MOQ) limitations.
Primary Industrial Applications
High-Pressure Piping Flanges & Industrial Valves: Live-loading elements that apply constant axial force to counteract thermal cycling and pressure spikes, maintaining secure seals in petrochemical and chemical processing plants.
Automotive Transmission Systems: Deployed in high-performance automatic transmissions, dual-clutch assemblies, and torque converters to provide immense return force for quick clutch plate disengagement within restricted axial spaces.
Bearing Pre-Load in Heavy Machinery: Positioned in industrial electric motors, large pumps, and CNC spindle assemblies to apply continuous axial pre-load, absorb micro-vibrations, minimize axial end play, and extend bearing service life.
High-Voltage Electrical Systems: Integrated into electrical contact mechanisms of high-voltage circuit breakers and power distribution switchgears to provide constant contact pressure, preventing electrical arcing and bolt creep.
