3876: ESTL 6X42X240

 

The loops are loose, and can therefore be turned to any position.

All dimensions are in mm
Dt = Wire diameter
De = Outer diameter
Lo = Free length
nv = No of active coils
c = Rate
Fo = Initial force, the force required before the spring starts to extend
Ln = Maximum permitted extended length for dynamic load
F1 = Spring force in Newtons at Ln = s x c + Fo
s = Deflection Ln - Lo
a = Inner diameter of loop
Material: Spring steel EN 10270-1-SH
Tolerances: SS 2384
Max. working temperature: 120 °C
