Nested Spirawave

• High Force
• High Spring Rate
• Short Deflection
• Precise Load/Deflection Characteristics

Nested Spirawave Wave Springs are pre-stacked in parallel, increasing the spring rate by a factor related to the number of turns.

f = Deflection (in)
H = Free height (in)
I.D. = Inside Diameter (in)
K = Multiple Wave Factor
L = Length, Overall Linear (in)
N = Number of Waves (per turn)
O.D. = Outside Diameter (in)
P = Load (lbs)
S = Operating Stress (psi)
t = Thickness of Material (in)
W.H. = Work Height (in) [H-f]
Z = Number of Turns
