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

[ ! ] Both ends of * marked springs are not ground.
[ ! ] 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).
[ ! ] O.D. Referenced Type is outer diameter prioritized.
● How to Determine the Number of Winding (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.
