A Guide on Different Kinds of Spring Washers

Spring washers are commonly used washers. Also known as disc springs or split ring washers, they are mainly used to prevent nuts/ fasteners from loosening grip because of vibration. These washers are flexible and thus they contract and expand depending on the movement of the equipment they are installed on. Owing to their flexibility, you can be sure that spring washers wouldn’t loosen up due to constant expansion or contraction of the machinery. However, you cannot just go for any spring washer to secure your machinery. Spring washer manufacturer provide different kinds of washers under this category to match different requirements. Let us take a brief look at the various kinds of spring washers and their uses:

Types of Spring Washers

There are mainly five types of spring washers. Each of these has its own unique design and functionality. Here is a look at what each one of them has to offer so as to help you pick the right piece:

Belleville Spring Washers

This washer is named after its inventor, Julien Belleville. Also referred to as conical spring washer or coned-disc spring, it comes in a convex or cone-shaped design. This type of washer is appropriate for equipment that experiences thermal expansion or contraction. They have the capacity to support huge loads with small installation space. Their annular shape ensures concentric force transmission. Top steel washer suppliers design Belleville washers that are sturdy and have a high service life. These are in demand in various industries.

Dome Spring Washers

Dome spring washers come with ground curves. They have a rather flat load-bearing surface. They support heavy load capacity and have a small deflection range. Usually crafted with stainless steel, they resemble the Belleville washers. The one clearly visible difference between the two is that the dome washers have rounded sides. You will also find dome spring washers made with rubber. These are more flexible however when it comes to durability, the stainless steel ones are a better choice. Yet, you may not be able to choose which one to opt for in certain cases because for some applications the stainless steel ones prove to be the correct choice and for many others the rubber ones are appropriate. You can use these anywhere a crescent spring washer comes in handy however a flatter surface needs to be created for proper installation and functioning of these washers. 

Wave Spring Washers

Also known as coiled wave springs, these washers have moderate load bearing capacity and medium deflection range. These are apt for thrust loading applications mainly where the radial space is limited. They support medium loads absorbing vibration as well as noise for smooth functioning of the application, have minimal sharp edge interference and are capable of rotating in two directions. They form a wave-like shape that aids in bearing the load. These washers act as a cushion and absorb the stress caused because of axial compressive loads. They mostly come in carbon and stainless steel. Reputed steel washer suppliers usually provide one with black oxide, yellow zinc or clear zinc finishing.

Finger Spring Washers

These have specially been designed for preloading ball bearings but also work well for various other applications. They comprise of three curved flanges. They have bent tags all around the washer’s circumference. This adds to the flexibility.

In addition to managing vibration, they help tackle a number of other issues for smooth functioning of applications. To begin with, they help lower damping and noise issues. They also reduce the wear and tear of the revolving parts as they lower the chances of skidding while rotating. Made with high-quality carbon steel, these are built to last. They also render life to the equipment they are fastened to. They can easily be installed using common hand tools.

Crescent Spring Washers

Also known as curved spring washers, they have a broad deflection range and provide support to small loads. Therefore, these are designed for equipment that support lighter loads and wide deflection range. They are known to offer a uniform spring rate within their deflection capacity. They have a flat appearance with a slight curve to ensure flexibility and offer lighter pressure. This is why they have been named curved washers. They are said to be suitable for load-cycling products. 

Quality is of Utmost Importance

Although spring washers are usually tagged as one however now you know there are different varieties under this category. It is important to choose the right type of spring washer in order to ensure it serves the required purpose. Nevertheless, whichever type you choose, make sure the spring washer manufacturer you opt for is trustworthy. Remember, if the washer lacks quality it wouldn’t serve the purpose even if you conduct detailed research and buy the most suitable type. Besides, a low-quality washer can have an adverse effect on the entire application. Conversely, a good quality one can increase the life of your machinery and offer a smooth experience.

Thus, we suggest not to compromise on the quality even if it requires shelling out a few extra bucks. There are many reputed steel washer suppliers that provide high-quality pieces that are durable and reliable. They last as long as your machine itself and aid in a seamless operation. A quick online search can help you reach the right product. Do not forget to read the customer reviews and check the ratings before you go ahead and buy the product. 

Bottom Line

So, you see there are five kinds of spring washers namely finger spring washers, curved or crescent spring washers, Belleville or conical spring washers, wave spring washers, and dome spring washers. Each of these has its own unique functionality and comes in handy for operating different applications. The aforementioned information about these washers should give you a clear idea about their usability. Understand your requirements well in order to find the one that fits your needs.
