DIN 2093 - Disc Springs (Belleville Washers)
Verified by Mel Sykes, Industrial Supply Chain Specialist - April 2026

Real-World Scenario
Imagine you're a procurement manager tasked with sourcing disc springs for a high-pressure valve assembly in an industrial setting. DIN 2093 - Disc Springs (Belleville Washers) You need to ensure the components meet stringent quality and performance standards to prevent costly failures. DIN 2093 comes into play here, providing critical specifications for Belleville washers.
What Does DIN 2093 Specify?
DIN 2093 specifies dimensions, tolerances, material properties, and testing methods for disc springs (Belleville washers). DIN 2093 covers a wide range of sizes to suit various applications, ensuring uniform quality across different manufacturers. The standard includes detailed tables that list specific values such as inner diameter. Outer diameter, thickness, free height, and load ratings.
Which Products Does DIN 2093 Apply To?
DIN 2093 applies specifically to Belleville washers, which are conical spring washers used in mechanical systems for clamping and positioning. These components are important in applications requiring precise force control and high reliability, such as in valve assemblies, gearboxes, and machinery mounts.
Key Technical Requirements
Key technical requirements under DIN 2093 include material grades like A4-70 stainless steel or EN8 carbon steel. Along with their respective mechanical properties. The standard also outlines tolerances for dimensions and load ratings, ensuring consistent performance across different manufacturers. For instance, the maximum thickness tolerance is ±0.1 mm, while the minimum yield strength should be 620 MPa for grade A4-70 stainless steel.
How Engineers Use DIN 2093 in Practice
Engineers use DIN 2093 to ensure that Belleville washers meet specific dimensional and performance criteria, thereby preventing failures due to improper selection or inconsistent quality. By adhering to the standard's guidelines, engineers can select washers that fit precisely within their assemblies, maintain correct preload forces, and withstand operational stresses without deformation.
Relationship to Other Standards
DIN 2093 complements other international standards such as ISO 7658 for Belleville springs, which also covers dimensions but may differ slightly in material specifications. Engineers often cross-reference DIN 2093 with industry-specific guidelines from trade bodies like the British Industrial Fasteners Association (BIAFD) and the British Fastener & Fixings Federation (BTMA). This ensures that all aspects of washer design and application are thoroughly covered.
Conclusion
DIN 2093 is an important reference for engineers involved in designing mechanical systems that rely on Belleville washers. At DIN 2093 - Disc Springs (Belleville Washers), by specifying critical dimensions, tolerances, and material properties, it helps ensure the reliability and performance of components across a wide range of applications.
