The standard values for the spring deflections and spring forces feature rounded average values.
F | = Force |
S | = Spring deflection |
De | = Outer diameter [in] |
Di | = Inner diameter [in] |
t | = Thickness of the single disc [in] |
h0 | = Maximum downward deflection of spring [in] |
S0.25 | = 25% of the maximum downward deflection [in] |
F0.25 | = Spring force with 25% downward deflection [N] |
S0.5 | = 50% of the maximum downward deflection [in] |
F0.5 | = Spring force with 50% downward deflection [N] |
S0.75 | = 75% of the maximum downward deflection [in] |
