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.
CAD files for stock and standard curved spring washers are available in our online store.
