The Difference Between Disc Springs and Belleville Washers - 1

WHITE PAPER The Difference Between Disc Springs and Belleville Washers by Nicholas Bunt, Product Specialist SPIROL International Corporation Disc Springs and Belleville Washers are both conically shaped spring washers typically made from spring steels and designed to be loaded axially. Both can provide a higher degree of force in a relatively compact area as compared to coil springs or wave springs. While the terms “Disc Springs” and “Belleville Washers” are often used interchangeably, there are some technical, design, and application differences between the two products: TECHNICAL DISTINCTIONS BETWEEN DISC SPRINGS AND BELLEVILLE WASHERS A defined list of standard Disc Spring sizes and associated load and deflection characteristics is available in DIN EN 16983 (formerly DIN 2093).
