Using for guide stem:
When auto spring without using guide stem ,according to the condition of auto spring ,there will be no stability and bending ,Using inner guide stem is the best choice.
>.When using inner guide stem,
Guide stem diameter should less 0.1mm than inner diameter for die spring
>.When using outer guide stem
Guide stem inner diameter should increase 1.5mm than spring outer spring
>.When using one guide stem
Guide stem diameter should more than 0.15mm than spring outer diameter
>.In practice,guide stem should more than pedestal
Guide stem height shoulg higher a half than free length of auto spring .It can increase service life.
>. auto springs only use for compression ,except extension ,torsion , or will be bending .transforamtion and scrap ,etc.
