Maximizing Load in Minimal Space
Disc springs, often referred to as Belleville washers, are engineered to handle massive loads within extremely restricted spaces. Unlike traditional coil springs, a disc spring provides a high degree of force with a very small deflection. These components are critical for maintaining bolt preload, absorbing shocks, or acting as thermal expansion compensators in high-pressure joints.
Understanding the force-deflection curve of a single disc is only the beginning. By stacking these springs, you can customize the spring rate and travel distance to meet your specific application requirements. Precise calculation of these stacks ensures your assembly remains stable under varying environmental stresses.

Critical Design Factors
| Factor | Engineering Impact | Performance Goal |
|---|---|---|
| Load at Flat | The theoretical maximum force when the disc is compressed fully. | Avoids overstressing. |
| Spring Rate | The amount of force required per unit of deflection. | Ensures consistent tension. |
| Fatigue Life | Determines how many cycles the spring can withstand before failure. | Maximizes longevity. |
| Hysteresis | The friction produced when stacking springs in parallel. | Accounts for damping effects. |
