What is the advantages of diaphragm spring compared to coil spring?

Diaphragm springs offer several advantages over coil springs, including a more compact design that allows for space savings in applications. They provide a linear force-displacement characteristic, resulting in consistent performance and better control over the spring's response. Additionally, diaphragm springs can accommodate higher loads and support greater deflections without permanent deformation, making them ideal for high-performance applications. Their ability to be preloaded and easily integrated into various mechanical systems further enhances their versatility.
