Belleville washers, also known as disc spring washers or coned disc springs, are conically-shaped washers designed to generate high axial loads within a small installation space. They are widely used to:

  • Compensate for thermal expansion

  • Maintain tension in bolted assemblies

  • Absorb shock and vibration

  • Improve joint integrity under dynamic conditions

Whether you require standard sizes or custom Belleville washers, we can meet your application needs with precision-engineered products.


Conical spring washers have a high spring rate that addresses thermal expansion and can generate extremely high loads in a small area. They can also absorb shock, provide damping and support high tension in bolted applications.
