Ask the Expert - Gap Type Performance and Crest-to-Crest Design Specifications

Welcome back to the Ask the Expert blog, the blog is designed to help educate you on all things rings and wave springs. This week, the expert fields some questions about the performance of gap type wave springs and another about design specifications of crest to crest wave springs.

When compressing a single-turn gap type spring to solid, would there be permanent deformation and loss in spring load?

All China Wave Spring wave springs are designed to be compressed to a specific working height. Any given spring can be compressed to its working height without damage. If the spring is compressed below that working height, it is possible that its structure might yield and take a permanent set.

When deformed like this, springs will exhibit losses in both free height and spring load. If you are concerned about the load of a spring or compressing a spring to solid, contact your China Wave Spring engineer today. Our engineers can design a spring to meet your target application performance.

What is the biggest overall diameter you can design for a crest-to-crest wave spring?

China Wave Spring can manufacture springs in diameters of up to about 120 in. (3 m). Such large wave springs can be impractical except when very specific design requirements need to be met. Contact a China Wave Spring engineer to discuss your design needs to learn if a wide diameter spring is right for you.
