What is a disc spring?
 

A disc spring provides great force for short travel and is therefore often used in constructions with a need for great force in minimal space. The disc spring has been designed as a conical spring washer that provides resistance when compressed, giving the spring its spring effect.

If one disc spring is not enough for the desired force and travel, it is possible to combine/stack several disc springs.

If 2 identical disc springs are inserted into each other, this provides 2 x the force and 1 x the travel.
If 2 identical disc springs are placed against each other, this provides 1 x the force and 2 x the travel.

Therefore, by combining identical stacks, you can adjust the force and the travel according to the task.

Black disc springs
 

Black disc springs are phosphated and oiled. This offers some degree of protection, but does not provide definite rust protection.

Stainless steel disc springs
 

Our stainless steel disc springs are made of AISI 302 material. We recommend using these in humid or wet environments.

Tolerances

Springs are dimensioned according to DIN 2093. The dimensions in the catalogue are unmachined measurements. Therefor measurements may differ from those in the catalogue tables. This applies to diameters and thickness.

The force is calculated theoretically. It is intended as a guide, with scope for large tolerances.

Datasheet and 3D CAD

If you want a PDF datasheet or a 3D CAD drawing of the spring in .step, .iges or .sat format, these can be downloaded for free by clicking on the 3D CAD symbol next to the item number in the table.

Service life of springs

The service life of a spring is generally very difficult to define. A large number of parameters come into play, and it is therefore impossible to define a service life.

Parameters with a significant influence on service life include: Installation, installation method, number of movements, vibrations, shocks, torsion, length of travel, non-axial travel, temperature, wear against other surfaces, environment of use, any cleaning agents, lateral impacts, etc.

Applying the maximum load to the spring or exceeding it will shorten its service life and may cause it to become permanently distorted.
