Nestawave™ Spring

Smalley’s Nestawave™ springs are nested wave springs in a Crest-to-Crest^® configuration. Coiled from a single, continuous piece of wire, they offer flexibility in spring rate design. By combining the deflection characteristics of a Crest-to-Crest Wave Spring with the force output of a Spirawave^® Nested Spring, the Nestawave delivers high force and significant travel in a compact design. Ideal for replacing stacks of Belleville washers, Nestawave springs reduce the risk of improper installation and simplify assembly.

Pairing the Deflection of a Wave Spring & Force of a Nested Spring

Springs Compare

Crest-to-Crest® wave springs are flat wire compression springs designed to save space while delivering reliable force. With multiple waves per turn stacked in series, they offer greater deflection and lower spring rates in a compact axial form, reducing axial space requirements by up to 50% compared to traditional coil springs.

Nested Spirawave^® springs are manufactured with multiple turns coiled together in parallel, creating a low-profile design that significantly increases force output while maintaining a compact overall height—ideal for applications requiring high load capacity in limited space.
