Wave washers, also referred to as wave spring washers, are some of the best load-bearing washers available. They are tiny metal discs with holes in the middle, similar to small doughnuts in appearance. These components are not flat, but have a wavelike look as their name suggests. They are designed to absorb stress when beneath a load, and their three-point contact area and curved design makes them ideal for the task. There are a number of different ways they are used.
Shock Absorbers
Wave washers can be built as shock absorbers to function like compression springs. If you are dealing with space limitations, they can be particularly effective.
Compensators
Wave washers can also assist in compensating for discrepancies in the operational capabilities of different mechanical devices. They can aid in preventing unwanted movement or vibrations if there are misalignments. If you are using bolts or screws, they can help stop any loss of friction that may cause the pieces to become unattached and fall out.

Improve Functionality of Ball Bearings
These parts can also be used to prolong the life of ball bearings and improve their performance. They help by lowering bearing noise and getting rid of any vibrations that might otherwise impact how the bearings function.
Selection Criteria
In order to pick the correct component, you need to know the required outside and inside ring diameters. The outside diameters define the circumferences of wave spring washers, and the inside diameters are set by the size of the bolt or cylinder they must encompass. Two other important criteria are the thickness and overall height of the pieces. They come in several different materials; steel is a good choice and particularly durable. A well-equipped construction supply store should have a wide range of them available in many different sizes.
Wave washers are versatile components that can be used for a variety of applications including shock absorbers, compensators and improving the functionality of ball bearings
Advantages of Springs
Springs have a wide application in many products as they are able to reduce the effect of shock by absorbing them. When the product experiences a shock, the spring compresses and relaxes to absorb it. Consequently, springs are important parts of vehicles.
The spiral spring is an example of a spring that can serve as an alternative to a battery. On an application of force, the spring can generate energy and release the energy in a constant manner. This makes it an important component of the mechanical watch.
Using spring can join two parts of a product or part together. For example, springs apply in a garage, door, and weighing machines to join two parts in order to function.
By its use in shock-absorbing capability, springs ensure that products that use them are stable. Product stability can also be a form of part friction and vibration reduction.
