Overlap type wave spring
TFC

Conventional Gap and Overlap Type Wave Springs are used in a wide variety of
applications. For short deflections and low to medium forces, they function with
precision and dependability.
With their smooth, circular coiled sinusoidal wave form, and rolled round edges of
pre-tempered raw material, our edge-wound Wave Springs offer many advantages
over die stamped products.
-Loads and spring rates are more accurate, more predictable, and may be
toleranced better than stampings.
-Gap & Overlap spring ends are free to move circumferentially as the spring
outside diameter grows during compression. This permits radial expansion
or diameter growth within a cavity, without the binding or hang-up normally
associated with die stamped wave washers.
-Edge-winding pre-tempered round edge flat wire produces wave springs with
uniform circular-grain microstructure and material surface free of pits, scratches,
cracks and other minute imperfections. By contrast, the stamping process forms a wavy washer with cross-cut grains, and subsequent manufacturing procedures
can lead to problems such as distortion and fatigue cracking.
