Disc Springs, also known as Belleville Washers and Belleville Springs, are discs with a slight cone shape, that deform to a shorter height when subjected to a load along their axis of symmetry. This elastic deformation characterizes the spring action.

　　Hebei OTHELLO’s disc spring fabrication is subject to exacting manufacturing and quality control standards. Materials used are generally in the annealed condition and hardened to within a range of Rc 44-51 depending on the material thickness. When required, disc springs are preset so that they will not significantly relax under load over time.

　　Disc springs can be a good design solution where the load required is high and the space available is limited. They can be tailored to provide loading profiles that are not feasible with coiled springs. Disc springs are used singly or in stacks to achieve a desired load and travel. Our disc springs are commonly used in high temperature/extreme pressure applications, pipe flange applications, bolted joint applications, heavy and light bolting applications, dynamic applications and bearing preloaded washer applications.
