Disc Spring Washer, with all of their variations, are among the most widely used tension generating washers. They are used for spanning alignment holes, distributing bearing loads and for generating and sustaining the tension needed to hold assemblies together. When loaded to flat, their yield point may be exceeded. These washers, however, are often used in applications where they function entirely within their elastic range.
By varying thickness and crown height relationships, design engineers meet a wide range of load/deflection requirement with Disc Spring washers.
