Allowable load, Rmax

Maximum allowable compression (stretch) value for this spring type

Operation deformation

2 types of springs exist: with allowable subsidence of  λmax=140mm and λmax=70mm


Spring height in free state. More...


Flexibility with given chain structure (type 1 - λmax=70mm, type 2 - λmax=140mm): 1, 2, 1+2=3, 2+2=4, 1+2+2=5, 2+2+2=6, 1+2+2+2=7, etc.

For, with chain structure 1+2+2=5, total operation deformation is 5*70 or 70+140+140=350mm. For springs with a allowable load of P=514kgf, flexibility is equal to  λmax/P = 350/514 = 0.6809 mm/kgf. More...
