Flange Disc Springs

Flange disc springs, or flange washers, are different from other Belleville washers and disc spring variations due to their unique shape, which includes a thin outside edge. In addition to structural differences, they tend to withstand extreme heat and pressure better than their alternatives.

Flange disc springs are precision-machined on all surfaces, with well-rounded edges. They can be used as a single disc spring or stacked on each end of a bolt, depending on estimated bolt elongation.

CAD files for stock and standard flange disc springs are available in our online store.

Flange Disc Springs Manufacturing

Flange washers are manufactured to include a small outside diameter for a pairing bolt size. They are often manufactured using carbon steel or stainless steel; however, they can also be produced from a variety of temperature and corrosion-resistant materials.


There are many characteristics of flange disc springs that make them attractive for various industries and uses. Our disc springs are commonly found in high temperature or extreme pressure situations, pipe flanges, bolted joints, heavy and light bolting, dynamic functions, and bearing preloaded washer applications.

Flange Disc Springs Configurations

Flange Disc Springs (NDS)

Flange disc springs (NDS) perform well in extreme conditions due to some key advantages, which are: maintaining bolt tension and gasket pressure around the flange and being able to automatically adjust for thermal variation, vibration, and mechanical shock stress.

NDS Flange Disc Spring

Flange Disc Springs (FL / MFL)

Flange Disc Springs (FL / MFL) have elastic mechanical elements which make them perfect for pipe flange applications. Reactive power keeps the bolt joint tight under all conditions.
