Using for guidestem
When spiral springcoil without using guide stem , according to the condition ofspiral spring coil, there will be no stability and bending , Usinginner guide stem is the best choice.
>.When using innerguide stem,
Guide stem diameter shouldless 0.1mm than inner diameter for spiral spring coil
>.When using outerguide stem
Guide stem inner diametershould increase 1.5mm than spiral spring coil outerspring
>.When using one guidestem
Guide stem diameter shouldmore than 0.15mm than spiral spring coil outer diameter
>.In practice, guidestem should more than pedestal
Guide stem height shoulghigher a half than free length of spiral spring coil .It canincrease service life.
>.spiral spring coilonly use for compression , except extension , torsion , or will bebending .transforamtion and scrap , etc.
