KF2-A
KALLER KF2-A Controllable Gas Springs with adjustable stroke length can be locked in the bottom position. The return stroke of the spring can be controlled.
The KF2-A 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. For certain applications, it is difficult to know in advance exactly what stroke length will be required. Therefore, the KF2-A controllable gas spring models offer adjustable stroke lengths within 15 mm.
The return stroke of the piston rod is controlled by a valve in the base of the spring.
For optimal performance, the full adjusted stroke should be used within ± 0.5 mm.
KF2-A adjustable stroke controllable gas springs are available according to the following table.
