These spring plungers can be used to compensate differences in height between the parts (up to 75 mm).
They fit all adapters with inside threading (SI-adapter).
The spring plungers are optionally available with an anti-rotation lock for use with oval suction cups (V-version). Please add order code "V".
For tougher applications we recommend the higher quality versions (H- and HV-version) with solid friction bearings and smooth plunger rods for gentle placement on sensitive parts.
Order example for torsion-proof version: FED-1825-HV
