Custom Borrelly Belleville Disc Springs

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 geometry enables high loads to be developed in a small space, so they are often used in assemblies requiring high stiffness. With excellent resistance to high stresses and strains, this type of washers is also highly capable of absorbing shocks and vibrations.

Our standard Belleville springs 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 their configuration, the stacking’s stiffness will vary.

Serial stacking 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.

Mixed stacking of Belleville disc springs: serial stacking of disc springs, themselves made up of disc springs stacked in parallel

Limitless stacking configurations

SAMPLE APPLICATIONS FOR Belleville disc springs

Belleville washers can be used for a variety of purposes: to solve problems of vibration, thermal expansion or relaxation, to maintain the load on a seal… They are commonly used in critical applications such as safety valves, clutch and brake mechanisms.

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.
