[ ! ]Both ends of * marked springs are not ground.

kgf (load) = N⋅mm (spring constant) × 0.101972 × F (Deflection)
[kgf]=N × 0.101972

● How to calculate the number of coils (reference value):
Total coils = solid length / wire diameter (d) - 1
Number of active coils = total coils - 2
* The values of the number of coils are for reference only. There may be some variations depending on the lot.

[ ! ]The values of solid length are for reference only. There may be some variations depending on the lot.
Using it compressed to the solid length may cause deformation or break after a few uses.
Be sure to use the springs within the range of the allowable deflection F max.(mm).
