Round Wire Coil Springs - L Dimension Configurable, O.D. Referenced Stainless Steel: Dimensional Drawing

[How to Calculate Spring Constant]
Spring Constant =	Max. Load (N (kgf))
	L × Allowable Deflection (%)

D Tolerance	⌀5 to 14	±0.3
D Tolerance	⌀15 to 27	±0.4
L Tolerance	Up to 50	±1
	51 to 100	±2
	101 to 250	±4

■Compression Springs

Type	Allowable Deflection	[M] Material
FWR	F = L × 60%	SWP−A
FWF	F = L × 50%
FWT	F = L × 40%
FUR	F = L × 60%	SUS304−WPB
FUF	F = L × 50%
FUT	F = L × 40%

[ ! ] Use within the range of allowable deflection %.
[ ! ] No grinding on both ends for d less than 0.9.
[ ! ] P is for reference only.
[ ! ] Load types A and B have a different number of coils, so the P dimension is different.
