LOADS
Load values shown are based on a service life of 50,000 cycles at 0.50 stress range.
For normal service, springs should not be compressed below L1. To determine the load at any working length use rate proposed deflection. P=(L-Lx) x R where Lx is the new load height. Reference only.
1 lb = 4.448 Newtons
1 Newton = 0.225 lb
Key of Measurements
D0 = Outside Diameter
d = Wire diameter
Sh = Approx. Solid Height
L0 = Free Length
L1 = Loaded Length
P1 = Load at L1
R = Spring Rate
