RotoPrecision Canada Features Smalley Steel Ring Wave Springs in Crest to Crest Flat Wire Compression Spring Configurations

Smalley Wave Springs: Crest-to-Crest® (with or without Shim Ends)

Crest-to-Crest wave springs, sometimes referred to as "flat wire compression springs" are pre-stacked rings in series which decreases the spring rate proportionally by the number of turns. Uses are typically applications requiring low-medium spring rates and large deflections with low-medium forces. As a replacement for helical compression springs, Crest-to-Crest springs provide similar forces yet occupy one-half (or less) the axial space. This allows for use in very strict space constraints where other springs simply cannot fit.

Among the major advantages of these springs, this design eliminates the need to keep the wave crests aligned. The need to use a key locating device, or to insert a shim between individual springs is not necessary. Because the spring is integrally formed, the wave peaks hold their configuration.

Crest-to-Crest wave springs will maintain the same force and load specifications of a conventional round wire spring but with the advantage of lowered and compacted operating heights, free heights and solid heights.

Crest-to-Crest Wave Springs are also available with squared-shim ends. Shim ends provide a 360° contact surface when compared to the wave point contact of plain ends. The shim-ends under load, more evenly distribute the springs force upon adjacent components. This feature is similar to the concept of double-disc grinding springs for a flat surface. Shim ends have also been used to affix springs to mating components, as a flat locating surface that may be attached by various methods in the assembly.
