Wave Spring with applied turns type Nested be wound from continuous flat wire. This is a cumbersome stacking a plurality of single-layer flat wire wave springs superfluous, if higher loads are specified in the application.
The spring rate of a Nested increases in proportion to the number of turns, so that high preload forces can be achieved. You can develop extremely high forces and still achieve the accuracy of a Circular-Grain® wave spring. Mostly, these springs are used, where over stacked disc springs a high, but at the same exact power is required.
Wave springs with applied turns are available from Smalley as custom-made. Feathers are available with diameters from 5.00 to 3000 mm.
