Belleville Spring Washers

  • Belleville Spring Washers

As an American Belleville spring manufacturer for nearly 70 years, Belleville spring washers have been an integral part of the Solon Manufacturing product family. While other companies provide washers, springs, and lock nuts, Solon’s standard for excellence continues to distinguish us from our competitors. Attention to engineering detail along with investments in technology and resources have given us the opportunity to rise to the occasion of meeting our customers’ needs—big and small—consistently.

Belleville spring, disc spring, and conical compression washer are all names for the same type of spring that is a conically shaped disc that will deflect (flatten) at a given rate. Belleville springs are characterized by four geometrical variables including outside diameter (OD), inside diameter (ID), thickness (T) and overall height (H) as shown in the diagram below.
