Belleville Washers

Belleville washers (also known as belleville disc springs) were invented by Julien-Francoise Belleville, who was awarded a patent in 1861 for a spring designed like a cone-shaped ring, capable of absorbing large axial forces with relatively small spring travel. Mubea has proudly manufactured Belleville springs in our Daaden, Germany plant since 1960.

Disc springs can be designed to meet the specific requirements of a variety of applications. These requirements can typically be met with springs from Mubea’s standard product line. Our standard product line includes disc springs designed per the requirements of DIN 2093, our own internal factory standards, as well as other special sizes. Disc springs from our standard product line are typically available from stock for immediate delivery.

Disc springs can also be designed with non-standard dimensions. Depending upon the availability of material and tooling requirements, delivery times may be longer.

Disc Spring Theory

belleville-washer-diagramAccording to the disc spring theory, Belleville springs (also known as Belleville washers) are shallow conical rings that are subjected to axial loads. Normally, the ring thickness is constant and the applied load is evenly distributed over the upper inside and lower outside edges. Disc springs are generally manufactured from spring steel and can be subjected to static loads, rarely alternating loads, and dynamic loads. Disc springs can meet the most stringent fatigue life and set loss requirements.

Creating a Belleville Disc Spring

Use the arrows below to navigate through how Belleville disc springs are made.

Common Belleville Washer Alloys

  • Copper Beryllium (CuBe)
  • Cr-Ni-Mo Stainless Steel
  • Nickel-Beryllium (NiBe)
  • Inconel
  • Nimonic
  • SAE Grade Steel
  • Chromoly Steel
  • More Materials

Belleville Washer Features

  • High temperature resistance & High fatigue life
  • Different assemblies can be designed to achieve the desired load characteristics
  • Special materials and various surface coatings available
  • Better space utilization when compared to other spring types
  • Low creep tendency with the correct dimensioning
  • High load capacity with a small spring deflection
  • DIN 2093 standards

3 cold- or hot-formed, turned on all sides, edges rounded R2 < 12.5 R2 < 12.5
*) Unless otherwise specified, the manufacturing process is left to the discretion of the manufacturer (see Section 5 in DIN 2093).
**) The specified values do not apply to shot-peened disc springs.

Belleville Washer Applications

Belleville springs have become indispensable in a host of applications and industries. Belleville disc springs are used everywhere from the automotive, food processing, and chemical industries and found in applications from boilers and industrial furnaces to superconductors and satellites.

They are commonly used in applications requiring high spring force and small deflections. The washers are also used in applications requiring a high degree of safety.

When the ratio De/t > 20, a larger tolerance for the free height is typically required. In this case, actual tolerances should be reviewed with Mubea.
