A disc spring (sometimes called a “Belleville washer” after the inventor) consists primarily of a convex disc supported at the outer periphery by one force and an opposing force on the center of the disc. Disc springs are used singly, or in stacks, to achieve a desired load and travel. The advantage of a disc spring is that it generates high force in a very short spring length and with minimal movement when compressed. All Century Spring disc springs are subject to exacting manufacturing and quality control standards. All discs are preset so that they will not significantly relax under load over time. Century Spring also offers pre-stressed disc springs specifically sized for use with bolts.
