The cylindrically curved disc spring, or curved disc washer, is well suited for applications requiring flexibility, light loads (from ounces up to about 100 pounds), and repeated cycles through a range of motion. The curved disc spring exhibits the most uniform spring which is constant over the widest range of deflection compared to the wave and Belleville type disc springs.
