Wave springs, though less known than traditional coil springs, offer a myriad of advantages across various industries. Their unique design and functionality make them an essential component in applications where space, weight, and efficiency are critical. In this blog post, we'll explore the benefits of wave springs and why they are becoming a preferred choice in modern engineering and manufacturing.

Wave springs are a type of compression spring made from flat wire that is coiled in a wave-like pattern. This design allows them to occupy significantly less axial space than conventional round wire coil springs while providing similar or even superior force and deflection characteristics.
One of the most significant advantages of wave springs is their ability to save space. Due to their flat wire design, wave springs can fit into smaller axial spaces compared to traditional coil springs. This space-saving feature is crucial in applications where compactness is essential, such as in automotive and medical devices.
Wave springs are lighter than traditional coil springs. The reduction in material usage not only saves space but also decreases the overall weight of the assembly. This benefit is particularly valuable in industries like automotive, where reducing weight can lead to better fuel efficiency and performance.
Despite their compact size, wave springs offer a wide deflection range. They can compress to a solid height and return to their original height without losing performance, providing reliable operation in dynamic applications. This characteristic is essential for applications requiring precise load control and consistent force over a long range of motion.
Wave springs provide a more uniform force distribution across their deflection range compared to traditional coil springs. This consistent force is beneficial in applications requiring precise load control and stability, such as in sealing applications and load-bearing structures.
Wave springs exhibit lower load loss over time compared to traditional springs. This means they maintain their force and deflection characteristics longer, leading to improved reliability and reduced maintenance costs. This durability makes them ideal for high-cycle applications where longevity is critical.
The manufacturing process for wave springs often involves less material and simpler production methods, making them a cost-effective solution. Additionally, their long lifespan and reduced need for maintenance further enhance their cost efficiency.
Wave springs can be customized to meet specific application requirements. They can be designed in various configurations, including single-turn, multi-turn, and nested wave springs, to provide different load and deflection characteristics. This versatility allows engineers to tailor the spring to the exact needs of their project.
The benefits of wave springs make them suitable for a wide range of applications across various industries:
Wave springs offer a host of benefits that make them a superior alternative to traditional coil springs in many applications. Their space-saving design, weight reduction, consistent force distribution, and cost-effectiveness make them an attractive choice for engineers and manufacturers. As industries continue to demand more compact, efficient, and reliable components, the adoption of wave springs is likely to grow.
By understanding and leveraging the advantages of wave springs, companies can enhance the performance, efficiency, and reliability of their products, leading to better outcomes and competitive advantages in their respective markets. Whether it's in automotive, medical, or electronics, wave springs are proving to be a modern solution for today's engineering challenges.
Spring operating height can be reduced by up to 50%.
In applications with tight space constraints, Crest-to-Crest wave springs optimize space concerns. The 'multiple waves per turn' design can offer the same spring force as a traditional coil spring, but at a reduced operating height. A reduction in operating height also decreases the spring cavity, yielding an overall smaller assembly size. Significant cost savings may be seen with a smaller, more light-weight assembly, as it takes less time and material to produce.

Quick and economical customization with Smalley's No-Tooling-Cost' edgewinding manufacturing process.
We can customize wave springs to fit your exact application requirements. The number of turns, end type, material type, and thickness are just a few parameters we can customize.
Our ability to accommodate virtually any design comes from our unique edgewinding process, where we take flat wire and then coil it on edge. With the freedom to coil to nearly any diameter (0.157 ' 120 in.; 4 - mm), we can efficiently optimize your design, all without the need for additional tooling.
Accurate and predictable loads are achieved by putting a tolerance on load(s) at specific working height(s).
Whether it's a static or a dynamic application, you're able to pinpoint the load that a wave spring outputs. This is because we tolerance critical load(s) at specified working height(s), so you can expect reliable, consistent performance in your application.
Wave spring technology is the trusted solution across many different industries and applications.
From small to large diameters, light to heavy-duty parts, carbon steel to exotic materials, wave springs has been the trusted solution for tens of thousands of applications. From everyday consumer products like the smartwatch on your wrist, or the coffee maker in your kitchen, to an oil well deep under the Earth's surface, to as high as, well, Mars, there is virtually no limit for wave springs. Below are some examples of common applications that utilize the benefits of a wave spring.
Flow Valves: As fluid pressure increases, a Crest-to-Crest Wave Spring precisely controls the linear displacement of the piston.
Pressure Relief Valves: Air pressure under the assembly causes the spring load to increase, which forces the plate away from the sealing surface and provides a pressure relief mechanism. As pressure decreases, the spring returns to its original work height, allowing the unit to seal again.
Face Seals: The wave spring applies pressure to precisely load against a mating surface, properly sealing fluids.
Vibration Isolators: Under constant loading, the isolator dampens vibration from equipment operation. Wave springs are used to provide precise and predictable loading.
Exotic alloys are an option for your applications in extreme environments.
There are a variety of key factors when it comes to choosing the right material for your application, including environment, budget, and cycle life. Using a material that is not optimized for the environment that it's in can lead to performance issues and decreased application life. If our carbon and 17-7 stainless steels do not meet your application's unique requirements, we offer a variety of custom materials.
From cryogenic to high temperatures, magnetically-sensitive to electrically conductive, deep-sea to outer space, our engineering team will tailor a wave spring fit for optimal performance.
We know it's important to ensure fit and function with prototype testing, so we offer free samples of our standards.
We also offer custom, economical prototypes that can be delivered to you in a short lead time with no minimum order quantity. This is a unique benefit of our edgewinding process, as traditional stamped parts have high up-front tooling costs, minimum order quantities, and traditionally longer lead times.'
