Product Description
GN722.4 Indexing Plunger, Stainless Steel, Weldable, with Rest Position and Latch
With indexing plungers GN 722.4, the plunger pin is actuated via the latch. 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 For this purpose, the latch is turned sideways after the locking pin has been retracted. The latch is held in this position by the catch recess 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 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.
