Wave Springs for Compact Energy Storage and Force Control
In many industrial applications, space is at a premium, and every component must contribute to overall system efficiency without adding unnecessary bulk. Wave Springs provide the perfect solution, offering compact force control and energy storage capabilities in a space-efficient design.
At Dongguan Sango Hardware Fasteners Co., Ltd., we manufacture high-quality wave springs designed for precision force applications and compact energy storage in mechanical systems, automotive parts, and aerospace components.
1. What Is a Wave Spring?
A Wave Spring is a type of compression spring made from wave-shaped material that offers high force generation in a compact, low-profile design. The wave pattern enables the spring to store energy in the same way as a traditional coil spring, but with less space and material usage.
🔩 Key Benefits:
- Space-saving design for tight applications
- Efficient energy storage in a compact form
- Reduced material usage while maintaining high performance
- Consistent force over compression cycles
- Ideal for applications requiring precision force control
2. Types of Wave Springs
🔹 Single-Turn Wave Spring
- Features a single wave for low-load applications
- Common in automotive components, valve assemblies, and electrical connectors
🔹 Multi-Turn Wave Spring
- Uses multiple turns of wave-shaped material to generate higher load capacity
- Ideal for high-tension applications, actuators, and shock absorbers
🔹 Retaining Ring Wave Spring
- Integrated design with retaining ring for secure mounting
- Used in precision machines, rotary systems, and bearing assemblies
🔹 Wave Washer Spring
- A thin, wave-shaped washer providing light compression
- Used in electrical contacts, brake pads, and pressure relief valves
🔹 Flat Wave Spring
- Offers flat, uniform compression with consistent load distribution
- Used in load balancing or force distribution applications
3. Key Applications of Wave Springs
Wave Springs are ideal for applications requiring high force in limited space:
- ⚙️ Precision mechanical systems (gears, actuators, cams)
- 🏎 Automotive suspensions and shock absorbers
- 🧳 Small electronics (mobile phones, power tools)
- 🧪 Medical devices (pressure valves, surgical instruments)
- 🧰 Mechanical assemblies in aerospace or industrial robots
- 🧼 Consumer products (watches, cameras, small appliances)
They are commonly used in applications with space constraints, where traditional coil springs would be too bulky.
