Indexing Plunger Stays Retracted


GN 817.8 Metric Size, Steel Indexing Plungers with Removable Pin Lock-out or Non Lock-out Type, are designed so that special versions of the indexing pins can be made economically in smaller unit quantities. They are assembled with a countersunk screw and can therefore be assembled several times. All parts are supplied individually as a disassembled set. If required, the indexing pins can be machined or made by the user.


Type C / CK indexing plungers are used for applications where the plunger has to stay in its retracted position. To achieve this, the knob is rotated by 90 degrees after being retracted and a notch keeps the plunger in position.


 The threaded body and lock nut are steel with a black oxide finish, while the plunger pin and countersunk screw are stainless steel.
