Precautions:

1. As illustrated in the drawing on the right hand, use over 3000,00-time condition will become the use around solid length,Around the solid length since the number of active coils will becomegradually coherent,the spring constant will become higher,and as illustrated,the load characteristic rises and becomes high stress,which would cause damage to products,please refrain from using over 300,000-time condition.
2. Use with any space will give impact and cause damage to spring.Besure to use with the initial deflecation of 1mm or more.
3. Bad parallelism of mounted surface would cause twisting or damage to spring .Be sre to check the parallelism.
4. Use without spring guide would cause twisting or damage to spring. Be sure to use spring guide such as shaft or outside diameter guide.
5. When the using environmental temperature becomes higher , substantial function loss will occur. Be careful about using environmental.
