Belleville springs are used to engage motion and force in various designs of clutches and brakes. Large stacks of heavy Bellevilles are designed into the latching devices on coke oven doors to ensure efficiency and help prevent loss of oven temperature. Belleville stacks are also employed in the tracks of rolling mills to help keep them balanced and produce consistent thicknesses of rolled steel.

Belleville spring force is used to maintain bolt pre-loaded in high vibration and thermal expansion and contraction in bolted connections. They are commonly used in heavy equipment to compensate for vibration and by power producing and transmission companies to keep a variety of bolted connections tight and secure. The most common of these involve transformers and bus bars.
