Recommendation for use :
Mounting : The spring is individually fitted between the stripper plate and the top plate thanks to retaining screw, guiding shafts or retainer.
Use conditions : Do not exceed the maximum loads to guarantee the lifetime of the springs. The springs have to be preloaded in the tools. When assembling the tool, there is no need to preload them, as in the rest position the stripper plate is not under spring pressure.
To order you need to indicate :
- The diameter
- The lenght
