HOME DAIspring Using precaution

When you use DAI Spring, please observe the following instructions.
Use Over Maximum Deflection (300,000-time Condition) (Use Near Closing Position)
As illustrated in the drawing on the right hand, use over 300,000-time condition will become the use around solid length. Around the solid length, since the number of active coils will become gradually coherent, the spring constant will become higher, and as illustrated, the load characteristic rise and becomes high stress, which would cause damage to product. Please refrain from using over 300,000-time condition.
Use without Initial Deflection
Use with any space will give impact and cause damage to spring. Be sure to use with the initial deflection of 1mm or more.
Use by Nipping Scrap or Foreign Artices
As illustrated in the drawing on the right side, when any foreign artcles is caught in spring, such part will not work as number of active coils, and the number of active coils will substantially become reduced, which would cause higher spring constant and damage to spring. Also, the solid length will become longer.
Use Where the Parallelism of Mounted Surface Is Not Good.
Bad parallelism of mounted surface would cause twisting or damage to spring. Be sure to check the parallelism.
Do not use without spring guide.
Use without spring guide would cause twisting or damage to spring. Be sure to use spring guide such as shaft or outside diameter guide.
Using Temperature
When the using environmental temperature becomes higher, substantial function loss will occur. Be careful about using environmental temperature.
