Indexing Plungers GN 817.8

Product description

Information

GN 817.8 indexing plungers have been designed so that special versions of the indexing pins can be made economically in smaller unit quantities.

If required, the indexing pins can be machined or made by the user as shown in the drawing above. They are assembled with a countersunk screw and can therefore be re-assembled several times. All parts are supplied individually as a disassembled set.

Lock-out types C / CK are used for applications where the plunger pin needs to stay in its retracted position. To achieve this, the knob is rotated by 90 degrees after being retracted. A notch keeps the plunger in the retracted position.
