Information

With indexing plungers GN 722.4, the plunger pin is actuated via the pull ring / latch. This is done either manually, with a cable or by means of an extended pull rod with hook. The ST version is designed for applications in steel construction, whereas the stainless steel version A4 is suitable for use in particularly aggressive environments.

The types with a rest position are used when the plunger pin should temporarily not protrude. For this purpose, the pull ring is turned sideways after the locking pin has been retracted. The ring is held in this position by the catch groove at the top of the guide.

The dimensional tolerances between plunger pin and guide are selected so that the functional reliability is guaranteed even after welding, applying a corrosion protection layer or in case of contamination.

For fastening by welding, the unmounted types AU / RU / CU / TU / EU / VU are particularly recommended to avoid changes to the microstructure of the material due to heating of the spring and plunger pin. In this case, the indexing plunger is assembled only after the surface treatment of the welded guide.
