What is a wave spring?

Hey there, spring enthusiasts and industry pros!

Let’s cut to the chase: We’re Zhejiang Lisheng Spring Co., Ltd. – and if wave springs are your thing, you’ve probably heard of us. As one of the world’s biggest players in this space, we’ve spent years perfecting the art of making these tiny but mighty components. Today, let’s dive into why our wave springs are the go-to for folks across 150+ countries. Spoiler: It’s all about packing big performance into smart, customer-focused designs.

First off, what is a wave spring, anyway? Think of it as a spring with a cool twist (literally). It’s a coiled flat wire with a wavy, sinusoidal shape – and that unique design? Total game-changer. These little powerhouses deliver the same force and deflection as a traditional coil spring but take up half the axial space. Ever struggled with tight radial or axial constraints? Yeah, we thought so. That’s why our wave springs are like the Swiss Army knife of the spring world – perfect for spots where every millimeter matters.

Curious how they work? It’s simpler than you might think. Unlike regular coil springs that rely on torsion (twisting), our wave springs operate by bending. When you apply an axial load, those waves flatten out, creating a steady, predictable, and repeatable force. No guesswork, no unevenness – just consistent load distribution through every bit of deflection. Neat, right?

We’ve got a wave spring for every job, too. Because let’s be real – one size never fits all. Here’s the lowdown:

• Single-Turn wave springs: A single continuous loop, ideal for short deflections, low-to-medium forces, and when precision is non-negotiable.

• Multi-Turn wave springs: Multiple waves per turn, making them a rockstar replacement for traditional coil springs. They save maximum space – trust us, your assembly line will thank you.

• Nested wave spring: Built tough by coiling multiple flat wire strands in parallel. When a standard multi-turn spring isn’t strong enough for high-load, heavy-duty tasks? This is your hero.

• Round-Wire wave spring: Made with round wire (surprise!) instead of flat, these are perfect for high-load, high-rate, low-deflection jobs. Plus, they’re a budget-friendly alternative to disc springs.

• Linear wave spring: Straight, wave-formed lengths that deliver linear load – great for preloading or spacing components along a straight line.

Now, let’s talk perks. Why do customers keep coming back?

• Less Space, More Power: Up to 50% less axial space than traditional springs, so you can build sleeker, lighter assemblies.

• Consistent Force: A linear, predictable spring rate means you get the exact load you need at a specific working height – every single time.

• Save Time and Money: Less material means lower production costs, and lighter products mean savings down the line. Plus, one wave spring can replace a stack of washers or disc springs – fewer parts, faster assembly.

• Built for You: We customize everything – number of turns, waves, material thickness, even the alloy – to match your exact load and deflection needs. Your project is unique, and your spring should be too.

It’s no wonder our wave springs pop up in all sorts of critical spots:

- Automotive : Transmission systems, clutches, brakes, powertrain components – keeping cars running smoothly.

- Aerospace : High-performance parts that thrive in the harshest environments.

- Medical Devices : Surgical tools, diagnostic equipment, even implants – where precision can’t be compromised.

- Fluid Power : Valves, pumps, face seals – anywhere a consistent, precise load is key.

- Electronics : Connectors, switches, and compact devices where space is at a premium.

- Bearing Preload **: Keeping ball or roller bearings under constant pressure to cut down on noise and play.

At the end of the day, being a global leader isn’t just about size – it’s about understanding what our customers need and delivering it, day in and day out. Whether you’re working on a cutting-edge medical device or a heavy-duty industrial machine, we’re here to make sure your wave spring works as hard as you do.
