DIN 2093 disc springs are designed for applications that require high axial force, compact installation space and predictable load-deflection performance. Compared with conventional coil springs, they can generate higher loads within a much shorter axial height.
Key features include:
High Load in Limited Space – The conical disc geometry provides high axial force with relatively small deflection and compact installation dimensions.
Standardized Dimensions and Performance – DIN 2093 defines dimensional, tolerance and quality requirements, making spring selection and replacement more consistent.
Flexible Load-Deflection Characteristics – Disc springs can be used individually or stacked in series, parallel or combined arrangements to achieve different force and travel requirements.
Suitable for Static and Dynamic Loads – With the correct material, stress level and configuration, DIN 2093 disc springs can be used for both static preload and repeated dynamic applications.
Multiple Material and Surface Options – Standard spring steels and application-specific materials can be selected according to temperature, corrosion resistance and fatigue requirements.
Standard and Custom Sizes Available – In addition to standard DIN dimensions, OD, ID, thickness, free height, material and load characteristics can be customized for special applications.
Reliable Preload and Compensation – DIN 2093 disc springs are widely used to maintain preload, compensate for thermal expansion, absorb dimensional variation and support stable axial loading.
These characteristics make DIN 2093 disc springs suitable for valves, bearings, clutches, braking systems, machine tools, heavy machinery, petrochemical equipment and power systems.
⊙ Inside diameter represents the interior hole size of the disc spring and should match your bolt size.
⊙ Outside diameter measurement is maximum outside diameter of the washer
⊙ Thickness indicates the material thickness and disc spring height when it is flattenaed
⊙ Height measurements represent coned disc spring height in an unloaded state
Dimensions and Designation


A disc spring is primarily defined by four geometrical dimensions:
| Symbol | Parameter | Selection Function |
| D / De | Outside Diameter | Determines available installation diameter |
| d / Di | Inside Diameter | Defines central clearance or guiding diameter |
| t | Thickness | Strongly influences spring force and stress |
| H₀ / l₀ | Free Height | Defines unloaded spring height |
| h₀ | Cone Height | Influences available deflection |
| s | Deflection | Working movement under axial load |
| F | Spring Load | Required axial force |
Correct selection should be based on the complete load-deflection requirement, not on outside diameter alone.
For replacement parts, provide the original DIN designation or measured dimensions. For new designs, provide the available installation space, target force and working deflection.

DIN 2093 / DIN EN 16983 classifies standard disc springs according to material thickness.
| Group | Thickness | Typical Construction |
| Group 1 | t < 1.25 mm | Disc springs without contact flats |
| Group 2 | t = 1.25–6 mm | Disc springs without contact flats |
| Group 3 | t > 6 mm | Disc springs generally manufactured with defined contact surfaces |
The correct group, geometry and manufacturing method depend on spring thickness and dimensional requirements.
For a specific part, HEGONG SPRING® can confirm the applicable DIN group according to the required size and drawing.
Standard industrial disc springs are commonly manufactured from spring steels selected for strength, elasticity and fatigue performance.
60Si2Mn / DIN 1.0909
Suitable for general industrial disc spring applications requiring reliable mechanical strength and elastic performance.
50CrV4 / DIN 1.8159
A widely used chromium-vanadium spring steel suitable for demanding static and dynamic spring applications.
For corrosive, elevated-temperature or cryogenic environments, alternative stainless steels and nickel-based alloys are also available through HEGONG SPRING®'s specialized disc spring ranges.

Available surface conditions and corrosion protection options include:
Polished finish
Phosphating and oil
Mechanical zinc plating
Chemical nickel plating
Dacromet / Geomet coating
Electrophoretic coating
The correct treatment depends on the base material, operating environment, corrosion exposure and dimensional tolerance requirements.
For aggressive chemical, marine or other highly corrosive environments, using an appropriate corrosion-resistant base material may provide better long-term performance than relying only on a coating.
