These hidden heroes are driving smarter, lighter, and cleaner solutions, from hydrogen fuel cells to high-performance machinery.
What are Disc Springs and why do they matter?
Disc springs, or Belleville washers, are small conical discs engineered to deform elastically under load. They deliver significant force in a minimal footprint, making them ideal for applications where both space and performance are at a premium.
By replacing bulky coil springs or complex mechanical systems, disc springs help reduce material usage and energy consumption, aligning perfectly with modern demands for efficiency and sustainability.
Emerging roles in hydrogen and clean tech
Looking ahead, disc springs are becoming critical in clean energy technologies such as hydrogen fuel cells and electrolysers. These systems rely on the precise compression of multiple stacked membranes or plates.
- Too little force? You risk gas leakage or uneven chemical reactions.
- Too much? The entire system could be damaged.
Disc springs are able to absorb thermal and pressure changes, offering uniform and consistent contact pressure over time and they tolerate corrosive environments also with high temperatures exceptionally well. Their ability to stack and scale in compact formats makes them uniquely suited for this new generation of energy systems.
Hidden Heroes in industrial innovation
Often hidden inside equipment, disc springs are the unsung heroes driving efficiency, safety, and durability. From automotive clutch systems to wind turbines and electrochemical reactors, their role is quietly essential.
They help:
- Extend equipment life
- Reduce maintenance cycles
- Support circular design through long service life and recyclability
