Technical description

Belleville disc springs, also known as Belleville spring washers, are conical spring washers. They are designed to be axially loaded, either statically or dynamically.

This type of washers is very resistant to high pressures and provides a low-flexibility spring effect in assemblies under heavy loads. In addition, they have excellent shock and vibration absorption properties.

Our Belleville springs can withstand very high loads in limited spaces and are manufactured in accordance with DIN 2093 specifications.

Belleville disc springs can be used singly and be centred either by the inside or outside diameter.

Belleville washers are frequently used stacked, either in the same direction (parallel stacking) or in alternating directions (serial stacking) as well as in combination (mixed stacking) according to the desired force-deflection characteristic. Depending on how they are stacked, they can provide larger deflections, larger loads or both.

Serial stacking of Belleville disc springs: the deflections are added, and the final force is equal to that of a single washer.

Parallel stacking of Belleville disc springs: the deflections are added, and the final deflection is equal to that of a single washer.

Serial stacking of Belleville disc springs: the deflections are added, and the final force is equal to that of a single washer.

Significant forces can be obtained
A very broad range of elasticity curves can be generated
High level of shock absorption in the case of parallel or mixed stacking
Limitless stacking configurations

Belleville spring washers are perfectly suited for compression spring applications requiring large loads in small spaces. They can be used for a variety of purposes : to solve vibration, thermal expansion, or relaxation issues, to maintain load on a seal or a gasket… They are commonly used in critical applications such as safety valves, clutch and brake mechanisms as well as industrial pipe systems.
