The Difference Between Disc Springs and Belleville Washers

Product catalog summary

Introduction
Disc Springs and Belleville Washers are conically shaped spring washers made from spring steels, designed for axial loading. They offer high force in compact areas compared to coil or wave springs. While often used interchangeably, there are technical and application differences between Disc Springs and Belleville Washers.

Technical Distinctions

Disc Springs: Used in dynamic loading/cycling applications with predictable fatigue life. Commonly found in pressure controls, vehicle braking systems, and other applications requiring repeatable force-travel relationships.
Belleville Washers: Primarily used in static applications, such as bolt fastening, where the load is static.

Material and Standards

Disc Springs: Made from high carbon steel (<1.25mm) or alloy steel (≥1.25mm), with thickness ranging from 0.2mm to 14mm. Governed by DIN EN 16983 & 16984 standards.
Belleville Washers: Typically thicker for a given outer diameter, governed by DIN 6796.

Application Recommendations
Choosing the right Disc Spring or configuration can be complex. It is advised to consult with Disc Spring Application Engineering experts to determine the optimal solution for specific applications.

Contact Information
SPIROL provides contact details for various international offices, offering support and expertise in Disc Spring applications.

Conclusion
Disc Springs provide innovative fastening solutions, reducing assembly costs and offering reliable performance in dynamic applications.

The Difference Between Disc Springs and Belleville Washers-1

WHITE PAPER The Difference Between Disc Springs and Belleville Washers by Nicholas Bunt, Product Specialist SPIROL International Corporation Disc Springs and Belleville Washers are both conically shaped spring washers typically made from spring steels and designed to be loaded axially. Both can provide a higher degree of force in a relatively compact area as compared to coil springs or wave springs. While the terms “Disc Springs” and “Belleville Washers” are often used interchangeably, there are some technical, design, and application differences between the two products: TECHNICAL DISTINCTIONS BETWEEN DISC SPRINGS AND BELLEVILLE WASHERS A defined list of standard Disc Spring sizes and associated load and deflection characteristics is available in DIN EN 16983 (formerly DIN 2093). Selecting the most appropriate Disc Spring or Disc Stack configuration can be challenging. It is recommended that designers partner with experts in Disc Spring Application Engineering to determine the optimum Disc Spring for a particular application.
