Technical drawing - Disc springs

Disc springs are a good choice in structures where high strength is required but space is limited. By combining several disc springs in layers it is possible to achieve varying force and travel.

We have most dimensions in stock, ready for dispatch. Please note we do not have prices for the largest disc springs. Please contact us for further information.

All our disc springs are magnetic - including those in AISI 316. This is due to the way they are produced. If non-magnetic disc springs are desired, please contact us at: [email protected]

Oiled spring steel & Stainless steel 302 - 8 digits in item number (e.g. 00600100) & Stainless 302 (00600100RF)
 

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.

50 CrV4 & Stainless 304 & stainless 316 (all with stock numbers such as 1200-420-50 & 1200-420-50-304 & 1200-420-50-316)
 

The springs 50 CrV4 & Stainless 304 & stainless 316 are dimensioned according to DIN 16983, which gives the following tolerances.

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.
