What are Wave Washers? Types, Function and Applications

Jan. 26, 2024

What are Wave Washers?


Wave washers, also referred to as coiled wave springs or simply wave springs, are accessories used in fastening applications to introduce a small gap between two surfaces. Named for their distinctive wave-like shape, these washers generate a spring force, making them effective shock absorbers.


In this article, we will delve into the functionality and uses of wave washers, exploring everything you need to know about these versatile fastener accessories.

How do Wave Washers Work?


Wave washers work by applying tension or storing energy when under force. When installed between two surfaces, they help prevent the assembly’s disintegration due to vibration or another movement.


Wave washers undergo axial strain when subjected to load placement, with the material attempting to revert to its original, free state. This spring-like action renders wave washers well-suited for shock absorption. Furthermore, these washers can serve as shims to level machinery or other equipment.


What Function Is Wave Washer?


Wave washers, also known as wave springs or coiled wave springs, are used to absorb stress due to axial compressive loads, acting as a cushion. The waves of the wave washer provide three-, four- or six-point contact that results in greater load bearing capacity and a medium range of deflection. The height and material thickness determine the load function.

Wave Washers: Applications in Various Functions


1. Shock Absorbers:


Wave washers can be designed to function as shock absorbers, effectively acting as compression springs. Particularly advantageous in scenarios with limited space, they provide efficient shock absorption.


2. Compensators:


Wave washers serve as valuable compensators, addressing discrepancies in the operational capabilities of different mechanical devices. They prove beneficial in preventing unwanted movement or vibrations caused by misalignments. When utilizing bolts or screws, they contribute to preventing the loss of friction that might lead to pieces becoming unattached and falling out.


3. Improving Functionality of Ball Bearings:


These versatile components contribute to enhancing the functionality and lifespan of ball bearings. By reducing bearing noise and eliminating vibrations, wave washers play a crucial role in optimizing the performance of ball bearings.

Considerations for Wave Washer Selection


When selecting wave washers for a specific application, several factors should be taken into consideration:




Choose a material that aligns with the environmental conditions and performance requirements of the application. Common materials include stainless steel, carbon steel, and beryllium copper.


Wave Type


Consider whether a single wave or multi-wave design is more suitable for the intended purpose. Single waves offer moderate flexibility, while multi-waves provide increased load-bearing capacity.

Size and Dimensions


Ensure that the dimensions of the wave washer align with the space constraints and requirements of the assembly. Proper sizing is crucial for optimal performance.




Wave washers, with their unique design and functional properties, offer versatile solutions in various industries and applications. Whether it's compensating for thermal expansion in electronics or providing shock absorption in automotive systems, these crescent-shaped washers play a vital role in maintaining the integrity and performance of mechanical assemblies.
