Despite an extensive standardprogram in tempered spring steel and stainless steelwithdifferent dimensionsand spring characteristics, some applications are not served with a standard stock flat wire wave spring. IntheseinstancesRotorClipofferstoproduceaspecialspringaccordingtocustomerspecifications.RotorClip’sproductionprocessdoesnot requirespecial tooling fornonstandardspecificationssothat theproductionofacustomspringisequaltothatofstandardparts.

TruWaveflatwirewavespringshelptosaveupto50%of axial space in your application when compared toconventional coil springs. The result is more compactapplications inwhich unnecessary space and thereforeexcess material of neighboring components can bereducedtoaminimum.Theflatwireeffectively reducesthesolidheightofthewavespringsothatwiththesameamountof turnsonecanvisibly reduce theworkheightwithout compromising the load or spring deflection.Anotheradvantageisthatonecanincreasethenumberof turnsof the springdesign in order todecrease thedeflectionperturnwhenthewavespringiscompressed.Thus, the spring rate is reduced proportionally to thenumber of turns and a flat linear charcteristic can begenerated.
