Compression disc spring

Disc Springs are conically-shaped precision components designed to be axially loaded. Disc Springs are often incorrectly referred to as belleville disc springs, belleville springs, belleville washers or simply conical washers. Disc Springs are unique and differ from other types of springs in that the force/deflection curves of Disc Springs are consistent and repeatable, and the minimum fatigue life can be reliably determined (per the standardized calculations of DIN EN 16984 (formerly DIN 2092)). Disc Springs can be statically loaded either continuously or intermittently, or dynamically subjected to continuous load cycling. They can be used singly or in multiples stacked parallel, in series or in a combination thereof to achieve the desired force-deflection characteristic. Disc Springs are preferred over other types of springs (such as coil springs, belleville washers, belleville springs and conical washers) when used in critical applications such as safety valves, clutch & brake mechanisms for elevators, and supports for industrial pipe systems due to their predictability, reliability and unparalleled fatigue life. The advantages of Disc Springs compared to other types of springs include the following: A wide range of load/deflection characteristics High load capacity with small deflection Space savings – high load to size ratio Consistent performance under design loads Longer fatigue life Inherent dampening especially with parallel stacking Flexibility in stack arrangement to meet your application requirements
