Disc Springs: A Definition and Description

Defining Disc Springs

In the middle of the nineteenth century the conical shaped spring disc was invented. This spring disc was subsequently termed a 'Belleville Washer' after the name of its inventor, Julian F. Belleville. In the 21st century, disc springs are used in endless devices such as spacecraft, satellites, medical devices, defence systems, automobiles and machine tools, to name a few.

Disc springs are conical shaped washers designed to be loaded in the axial direction only' 'F'. Disc springs can be statically loaded, either continuously or intermittently, or cyclically deflected i.e. dynamically loaded.

Buy using disc spring singularly or stacked in combinations variable spring characteristics can be achieved to suite a given application.

Disc Springs are conically-shaped precision components designed to be axially loaded. Disc Springs are often incorrectly referred to as belleville disc springs, belleville springs, belleville washers or simply conical washers.  Disc Springs are unique and differ from other types of springs in that the force/deflection curves of Disc Springs are consistent and repeatable, and the minimum fatigue life can be reliably determined (per the standardized calculations of DIN EN (formerly DIN )). Disc Springs can be statically loaded either continuously or intermittently, or dynamically subjected to continuous load cycling. They can be used singly or in multiples stacked parallel, in series or in a combination thereof to achieve the desired force-deflection characteristic.

Disc Springs are preferred over other types of springs (such as coil springs, belleville washers, belleville springs and conical washers) when used in critical applications such as safety valves, clutch & brake mechanisms for elevators, and supports for industrial pipe systems due to their predictability, reliability and unparalleled fatigue life.

The advantages of Disc Springs compared to other types of springs include the following:

  • A wide range of load/deflection characteristics
  • High load capacity with small deflection
  • Space savings ' high load to size ratio
  • Consistent performance under design loads
  • Longer fatigue life
  • Inherent dampening especially with parallel stacking
  • Flexibility in stack arrangement to meet your application requirements

SPIROL offers the full range of DIN EN (formerly DIN ) Group 1 and 2 Disc Springs in Series A, B, and C.  In addition to the DIN specified sizes, SPIROL stocks its own standard size range in outside diameters from 8mm to 200mm in order to meet the diverse needs of its customers. SPIROL standard Disc Springs meet all material, dimensional tolerance, and quality specifications as laid out in DIN EN (formerly DIN ) but in diameter and thickness combinations that are not included in the DIN standard.

SPIROL also offers a line of austenitic Stainless Steel Disc Springs.

SPIROL supplies single Disc Springs, as well as Pre-stacked Disc Springs in custom configurations, packaged in shrink wrap with a perforated tab for easy of assembly.

Select from our expansive standard offering, or take advantage of our complimentary Application Engineering support and allow us to work with you to help determine the most appropriate Disc Spring or Disc Spring Stack for your specific application and assembly needs!
