Types of Spring Washer

The spring washers produced by our company mainly include the following types:

 
 

Conical Washer

The conical washer, also known as a belleville spring washer, is a uniquely shaped disc that can be used alone or stacked in series. When compressed, the washer deforms until it flattens, storing energy in the form of a preload, which ensures a tight seal.

 
 
 

Wave Spring Washer

The wave spring washer is a fantastic component used between bolts and nuts, providing just the right amount of springiness to handle vibrations, shocks, and even the occasional bumpy ride. They are often used to secure machine parts, automotive components, aerospace devices, and electronic parts.

 
 
 

Conical Belleville Spring Washer

The conical belleville spring washer is a widely used mechanical component in many types of machinery. Its main function is to provide preload, preventing bolts or screws from loosening. The washer has a unique double-cone shape, made up of several spring discs, which gives it greater load-bearing capacity than standard washers.

Advantages of Spring Washer

 

 

Vibration Resistance

The spring-like action of spring washers helps to absorb and dissipate the effects of vibrations, preventing the loosening of bolts and maintaining the integrity of the connection.

Thermal Expansion Compensation

Spring washers can accommodate changes in the size and shape of components due to thermal expansion, helping to maintain the desired tension and clamping force.

Increased Clamping Force

Certain types of spring washers, such as conical and disc spring washers, can generate a high level of clamping force, making them suitable for applications that require a secure and reliable connection.

Improved Reliability

By preventing loosening and maintaining the proper tension in fasteners, spring washers help to ensure the long-term reliability and performance of mechanical systems.

Cost-Effectiveness

Compared to other locking mechanisms, spring washers are generally a cost-effective solution for maintaining the integrity of connections, making them a popular choice in a wide range of industries.

 

Spring Washer Installation Steps

Place the spring washer under the threaded fastener in place, with the concave side of the washer facing the flange or bearing surface. The convex side of the washer should make contact with either or both of the nut and the bolt head. When used correctly, a spring washer will hold the nut or other threaded fastener in place. To help it accomplish this, put the spring washer on first, below the fastener.


Ensure that the washer is flush against the fastener and the other surface to create a tight connection.


Tighten with the proper torque for reliable hold and a safe application. You can accomplish this by turning a wrench or ratchet clockwise. For a specific torque value, use our detailed guide that breaks down how to calculate torque to tighten bolts.


As a final step, examine the washer and make sure that it is working correctly. If the washer is not working correctly, loosen the nut or threaded fastener and fix the washer.

 

Spring Washer Material
 

Steel is the most common material for spring washers due to its ease of process and its high tensile strength. Chrome vandium alloy is a higher quality steel with a good through-hardening capability; it is used to make very thick spring washers. Specialty washers offering corrosion resistance include steel-nickel alloys. High-temperature applications incorporate chrome-molybdenum into the material structure to create washers that can operate over 400°C.

 

Copper alloys offer non-magnetic yet electrically conductive washers, along with some corrosion resistance. These alloys have lower strength values than steel.

 

Nickel-chrome and nickel-chrome-cobalt alloys have very high tensile strengths with very low elastic ratios. These washers will have more set if overloaded, but they have extreme longevity and corrosion resistance. They can also operate in a large range of temperatures, from absolute zero to over 700°C. These expensive alloys are difficult to manufacture.

FAQ

 

Q: How do spring washers work?

A: Spring washers work by creating a constant tension or pressure between the mating surfaces of a bolt and the surface it is tightened against. This tension is generated by the spring-like action of the washer, which allows it to compress and expand as the bolt is tightened and loosened.

Q: In what applications are spring washers commonly used?

A: Spring washers are used in a wide range of industries and applications, including the automotive industry, construction and heavy equipment, electrical and electronics, aerospace and defense, machinery and industrial equipment, and furniture and appliances.

Q: How do you choose the right type of spring washer for an application?

A: The choice of spring washer type depends on the specific requirements of the application, such as the level of vibration, the amount of clamping force needed, the available space, and the environmental conditions. Factors like the size and material of the bolt, the surface finish, and the load-bearing requirements should also be considered when selecting the appropriate spring washer.

Q: Can spring washers be used with any type of bolt or fastener?

A: Spring washers can be used with a variety of bolt and fastener types, including hex bolts, machine screws, and other threaded fasteners. However, the specific type and size of the spring washer should be selected to match the dimensions and requirements of the particular bolt or fastener being used.

Q: How do you install spring washers correctly?

A: When installing spring washers, it is important to ensure that the washer is positioned correctly between the bolt head or nut and the surface it is tightened against. The serrated or toothed edges of the washer should be facing the surface to be secured, allowing the teeth to bite into the material and create the necessary tension.

Q: What is the difference between a spring washer and a flat washer?

A: The main difference between a spring washer and a flat washer is their function and design. A flat washer is a simple, non-spring-loaded washer that is used to distribute the load of a bolt or fastener over a larger surface area.
