Custom Borrelly Belleville Disc Springs

Technical description

Belleville washers are spring washers with a conical configuration that perform a spring function.

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, they are also highly capable of absorbing shocks and vibrations.

Our standard Belleville spring washers are designed to DIN 2093.

Belleville spring washers can be centred either by the inside or outside diameter.

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

Empilage mixte de rondelles Belleville : empilage série de plusieurs groupes de rondelles, eux-mêmes constitués de rondelles empilées en parallèle

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

SAMPLE APPLICATIONS FOR Belleville spring washer

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.
