Belleville Washers: What Are They For?

Belleville Washers: What Are They For?


Disc spring is a mechanical component within the washer family, are easily recognized by their distinctive conical shape, which gives the part elasticity and the capacity to absorb high loads even in a small housing space.

This item is typically used in bolted joints subjected to dynamic loads because it has high resistance and the ability to dampen vibrations, providing a cushioning effect, in addition to a low tendency to deform.

These characteristics make them the ideal item for various industry sectors.

Belleville washers can be classified into three groups, as specified by DIN 2093, based on the thickness of the part.

The first group includes all items with a thickness of less than 1.25 mm, the second all washers with a thickness ranging from 1.25 mm to 6 mm, and the third and final group includes parts with a thickness from 4 to 16 mm.

Uses of Belleville Washers



This type of part is primarily used in the following sectors: railway, automotive, earth moving, energy, oil, and construction, precisely for their high load-bearing capacity with minimal space requirements.

Incorrect assembly of these items could lead to malfunctions, interruptions in operation, or production.

How Are Belleville Washers Assembled?



The assembly of these parts can be envisioned in various ways: a single spring, in packs in the same direction, alternately overlapped, or in alternate packs.

It is of fundamental importance to maintain contact between each spring and the next to avoid even minimal displacements in case of stresses.

Given the wide range of sectors in which Belleville washers are used, they are available in steel and stainless steel.
