KF2 1500-025
KALLER KF2 Controllable Gas Springs can be locked in the bottom position. The return stroke of the spring can be controlled.
The KF2 controllable gas spring series consists of a family of gas springs for use in metal forming dies, whose piston rods can be locked at bottom dead center (BDC). The KF2 springs can be used where, for instance, the blank holder should be locked in its bottom position to avoid deformation of the formed part.
The return stroke of the piston rod is controlled by a valve in the base of the spring. The KF2 controllable gas springs are available with stroke lengths from 5 to 160 mm. As the stroke length always has to be fully utilized, the springs can be ordered with any stroke length between 5 and 160 mm (in increments of 1 mm).
For optimal performance, the full stroke should be used within ± 0.5 mm.
