Due to these properties, the original disc spring has found applications in such a wide range of technological fields that it is now difficult to find an area where it isn&#;t utilized.

The importance of springs for the functioning of machines and devices is often underestimated. Any impairment of these components can lead to malfunctions and even the failure of entire systems.

Springs are typically classified based on the type of stress they endure. As a disc-shaped bending spring, the disc spring holds a special place among springs. By modifying geometric parameters, it&#;s possible to tweak the characteristic curve of a spring from linear to strongly degressive.

• High Spring Force with Minimal Travel: A disc spring can exert a high spring force over a small travel distance, making it ideal for storing potential energy.
• Versatility in Applications: Apart from (quasi-)static usage, disc springs are frequently employed in dynamic applications.
  

When disc springs are used under sinusoidal oscillating stress, fatigue and fatigue strength diagrams are crucial for safe design. Generally, the dimensions should allow the spring to handle more than 2×10^6  load changes.

• Compliance with Specifications: Adhering to guidelines for the use of guide elements and setting the minimum preload force is particularly crucial in dynamic applications.
• Safety Factors for Non-Sinusoidal Loads: If the load type deviates from sinusoidal oscillation, theoretical parameters must be supplemented with appropriate safety factors.
  

Due to the geometry of a disc spring, multiple elements can be layered:

• Alternating Directions: When disc springs are arranged in alternating directions, the spring travels add up if the force remains the same.
• Same Direction: When arranged in the same direction, the spring forces add up if the spring travel remains the same.
  
• This layering capability allows for the creation of a wide variety of characteristic curves. By arranging disc springs of different thicknesses or using intermediate rings of different thicknesses, even progressive characteristic curves can be achieved. This flexibility makes the disc spring suitable for a wide range of applications.

If the disc springs listed in this catalog, manufactured according to DIN EN standard (formerly DIN ), do not meet your requirements, please contact us directly. Our technical advisory team is at your side and will be happy to design the right disc spring according to your specifications. The earlier we are involved in the development process, the better we can support you with our know-how and experience.

Choosing the right disc spring is crucial to avoid high follow-up costs, such as damage to your product&#;s reputation or replacement expenses. Investing in a higher-quality disc spring is often more economical in the long run. Here are the most important selection criteria to consider:

• Manufacturing Quality: Ensure the manufacturing process meets quality requirements. Using a high-quality disc spring that meets these requirements can prevent failures and ensure longevity. We are available to advise you on the right choice.
• Is the Disc Spring Set? Verify if the disc spring is set. Some low-cost suppliers skip this step to cut costs. If not set properly, the disc spring may settle after the first load, compromising its performance.
• Material Selection: Choose a suitable material, especially if the spring will be exposed to high temperatures or corrosive environments. Refer to specific guidelines for material selection.
• Surface Treatment: Select an appropriate surface treatment for corrosion protection. Proper surface treatment can significantly enhance the spring&#;s durability and performance.
