Disc Springs/Belleville Washers/Heavy Duty Belleville Washers

Disc Springs, also known as Belleville Disc Springs, Belleville Springs, Belleville Washers, or Conical Washers, are precision components designed for axial loading. Unlike other types of springs Disc Springs have consistent and repeatable force/deflection curves, making them highly reliable. 

These springs can be statically loaded or subjected to continuous load cycling. They can be used individually or stacked in parallel, series, or combinations to achieve the desired force-deflection characteristics.

The advantages of Disc Springs over other types of springs

1. Wide range of load/deflection characteristics
2. High load capacity with minimal deflection
3. Consistent performance under design loads
4. Long fatigue life
5. Ability to stack to meet application requirements

What are disc springs?

An optimal choice for high load applications, disc springs are especially suited when available space is at a premium. 

Conical disc springs comprise a convex disc with its outer edge operating in opposition to its centre. This generates a high spring force inside a short movement area. The configuration allows disc springs to support much higher loads with less solid height and relatively little deflection compared to standard springs with a helical design.

Common applications of disc springs 

Exceptionally versatile, disc springs see frequent use in many plant and manufacturing applications. Common uses for the components include thermal expansion, controlling excess vibration, bolt creep problems, overload clutches, energy storage, spring actuated brakes and valves.

Can you stack disc springs?

Stacking disc springs is a common practice that allows users to customise their impact. By stacking springs, the overall force and deflection of the assembly can be modified to fit specific requirements. 

It’s important to note that the way stacked springs are oriented has a bearing on how they behave. The series method involves stacking springs in alternating, opposite directions. This will multiply the total deflection while keeping the load needed to compress them equal to one single spring. 

In the parallel method, disc springs are all stacked in one direction. This multiplies the load capacity but keeps the total deflection identical to that of a single spring. 

The third method, series-parallel, combines the two options, multiplying both the deflection and the load. This is used in more complicated applications.

How do you know which disc spring you need?

To identify the precise disc spring needed for an application, users must determine their exact load requirements, deflection, available space and operating environment.
