What are Gap Wave Springs?

Gap wave springs are a type of mechanical spring characterized by their distinct wave-like configuration. These springs are often used in applications where space is limited, high load capacities are required, and a consistent spring force is crucial. They are known for their ability to withstand high stresses, making them ideal for demanding applications. They are commonly referred to as wave springs or simply gap springs.

Design and Construction

Gap wave springs are meticulously engineered to achieve their remarkable properties. The key element in their design is the wave pattern, which is created by a series of bends or curves in the spring material. This wave-like structure allows the spring to compress and expand in a controlled manner, ensuring a smooth and consistent force output. These springs can be manufactured from a variety of materials, with the most common being spring steel. The specific material selection depends on the intended application and the required properties, such as strength, corrosion resistance, and temperature tolerance.

Advantages of Gap Wave Springs

Gap wave springs offer several advantages over traditional coil springs, making them a preferred choice in various engineering scenarios. These advantages include:
