Tension springs are helical springs that bear axial tension, and extension springs are generally made of round cross-section materials. When not under load, the coils of the tension spring are generally tight and there is no gap.

The initial tension of the tension spring:
The initial tension is equal to the force required to pull apart the springs that are close to each other and the initial tension occurs after the spring is rolled into shape. When the tension spring is made, the initial tension of each tension spring is uneven due to the difference in steel wire material, wire diameter, spring index, static electricity, grease, heat treatment, electroplating, etc. Therefore, when installing tension springs of various specifications, they should be pre-tensioned to a slight distance between each pair of turns. The force required at this time becomes the initial tension.
Initial tension=P-k X l=maximum load-spring constant X extension length
Spring constant: expressed in k, when the spring is stretched, the load for each additional 1mm distance (kgf/mm)
Spring constant formula (unit: kgf/mm): k=(GXd4)/(8XDm5XNc)
G: rigidity modulus of the wire; d: wire diameter; Dm: middle diameter = outer diameter-wire diameter; Nc: effective number of turns = total number of turns -2.
