Belleville Washers

Belleville Washers
Belleville washers â„¢ are disc-shaped washers with a convex shape. They are used for spring applications where heavy forces are needed in small deflection areas. Different stacking methods and stack heights can be used to change the forces, along with altering the material type, size, OD and ID. Each washer within a stack should be considered as one coil, as with a compression spring design.
Designing Belleville washers can be complicated due to the many variables that can change within Belleville Washer design curves. The manufacturing process of Belleville washers can be costly, requiring more complex tooling than compression springs. Companies that specialize in Belleville Washers stock numerous sizes. In order to save money in design, prototype and production cost, it is recommended that these companies that specialize in Belleville washer production should be consulted first as a source for Belleville washers prior to seeking a specially designed Belleville washer.
