Discover more about the Belleville Washers range.

Belleville Washers (also called Conical Washers or Belleville Springs) are part of our extensive range of Washers and they are designed to act as cone-shaped springs, and are often used to pre-load a fastener. Both our Stainless Steel Belleville Washers and Acetal Belleville Washers are intended to be flexible, and owing to their conical shape, create near-perfect concentric force dispersal.

This type of Compression Washer is highly versatile, and can be installed in different positions for different effects. Two Belleville Washers installed facing the same direction will create a more rigid pre-load structure, whereas two washers facing in opposite directions will create a more flexible spring. Multiple Belleville Washers can be used in series to create very precise preload forces, increasing or decreasing the force dependent on the direction of each washer.

Materials

These components can be manufactured from Acetal, A2 and A4 Stainless Steel as standard, with Chemical Matte Black Coatings available on the Stainless Steel options.

Metric Conical Washers

Accu's Belleville Washers are available in metric diameters of between M3 and M24, and are manufactured to a general tolerance of +/-0.13mm.
