Disc Spring
What is a Disc Spring Washer ?
Disc Spring Washer, also known as a Belleville Washer, is a type of washer with a conical, disc-like shape that functions as a spring. It is designed to provide high load-bearing capacity, absorb shocks, and maintain consistent pressure in mechanical assemblies, especially in situations where space is limited.

Disc Spring DIN 2093 :
Disc Spring DIN 2093 is a German standard that specifies the design, materials, and performance characteristics for Disc Springs. It’s designed to this standard are commonly used in applications requiring high load-bearing capacity and consistent spring performance in a compact form.
● Disc Spring DIN 2093 Geometry and dimensions :
Outer diameter (OD) – The total diameter of the Disc Spring.
Inner diameter (ID) – The hole in the center of the Disc Spring, typically designed to fit around a bolt or shaft.
Thickness (t) – The thickness of the spring at the thickest part of the cone.
Free height (h0) – The height of the Disc Spring in its uncompressed state.
Spring deflection – The amount by which the Disc Spring deflects under a given load. This property defines how much the spring can compress under a load and is essential for its performance.
● Disc Spring DIN 2093 material specifications :
The materials used for DIN 2093 Disc Spring is critical for their strength, fatigue resistance, and durability. Common materials include :
Spring steel (e.g., 65Mn, 60Si2MnA) – Offers a good balance of strength, flexibility, and fatigue resistance.
Stainless steel (e.g., AISI 301, AISI 304, AISI 316) : Used for corrosion-resistant applications.
Alloy steel – For high strength applications. Materials should meet the mechanical properties specified by the standard, such as tensile strength, yield strength, and hardness.
● Disc Spring DIN 2093 load deflection characteristics :
Load capacity – DIN 2093 defines the load-bearing capacity of the Disc Spring for specific dimensions. It helps ensure that the spring can withstand the required loads in dynamic and static applications.
Spring rate – This is the rate at which the spring deflects under load (force per unit of deflection). The spring rate depends on the material, the thickness of the disc, and the design.
Deflection – The deflection (compression) of the Disc Spring under a load is important for applications requiring shock absorption or preload maintenance.
● Disc Spring DIN 2093 performance in various environments :
Disc Springs conforming to DIN 2093 are designed to handle varying environmental conditions, such as :
Temperature fluctuations – The materials must retain their mechanical properties even at extreme temperatures.
Corrosion resistance – Stainless steel options offer resistance to corrosion in environments where moisture or chemicals may be present.
Vibration and dynamic loads – The springs should perform reliably under fluctuating loads and vibrations.
● Disc Spring DIN 2093 manufacturing and quality control :
Disc Springs must be manufactured with high precision to meet the required specifications and tolerances outlined in DIN 2093. Quality control tests include load-deflection tests, fatigue tests, and visual inspections to ensure the springs meet the standard’s mechanical and performance characteristics.
Disc Spring uses :
Disc Springs are widely used across different industries due to their ability to provide high load-bearing capacity, absorb shocks, and maintain consistent pressure or preload in compact spaces. Below are some of the primary uses of Disc Springs :
● Disc Spring uses in mechanical engineering :
Bearing Preload – Maintains axial load on ball or roller bearings to reduce vibration and extend bearing life.
Clutches & brakes – Applies constant pressure in automotive clutches or rail brake systems.
● Disc Spring uses in Automotive industry :
Suspension systems – Acts as a compact shock absorber.
Valve train – Used in some high-performance engines to maintain valve tension.
● Disc Spring uses in industrial machinery :
Bolt preloading – Prevents bolt loosening due to vibrations or thermal cycling.
Press tools – Applies consistent force for punching or forming.
● Disc Spring uses in electrical & electronics :
Circuit breakers – Ensures contact pressure in electrical connections.
Thermal switches – Reacts to expansion and contraction due to temperature changes.
● Disc Spring uses in Oil & Gas / Energy :
Pipeline flanges – Maintains sealing pressure in high-temperature, high-pressure environments.
Safety valves – Controls load and ensures precise valve actuation under varying conditions.
● Disc Spring uses in Aerospace :
Landing gear systems – Absorbs high impact loads during touchdown.
Actuator systems – Provides controlled movement and load distribution.
