A Belleville Spring Washer is a washer in the form of a cone, having constant material thickness, and used as a compression spring. Unlike compression springs Belleville Spring Washers provide exceptionally high loads in restricted spaces. Load flexibility can be varied by stacking the washers in various configurations (see below).
