kgf (Load)=N/mm (Spring Constant)×0.101972×F (Deflection) E Both ends marked with * are not ground.
ICalculation method of coils (reference value):
Load (kgf)=Load N×0.101972 Total number of coils=solid length÷Wire diameter (d)-1
Effective coils=Total number of coils-2
* The number of coils is a reference value. There may be some variations depending
on the lot.
E The values of solid length are for reference only. There may be some variations
depending on the lot.
And if it is used under the limit condition of solid length, the spring may be
deformed, or damaged after using only a limited number of cycles.
E Always use within the allowable deflection Fmax.(mm).
