GN 613 Indexing Plunger without Rest Position

Type G or GK of the GN 613 indexing plungers have been designed for applications where the indexing plunger is not operated with the standard knob. The indexing plungers are designed such that the plunger set in the end position (spring is "on block") can also absorb axial forces. For applications in which these forces are substantially above the tensile force applied by the operator (Type G), GN 817 indexing plungers are to be preferred. A special installation tool GN 613.1 is available. Two slots are provided in the upper end of the body which are accessible with the knob in its retracted position.
