Page 894 | 3.1 Indexing, Locking, Blocking with Pins and Ball-Shaped Elements Type G or GK of the indexing plungers GN 613 have been designed for applications where the indexing plunger is not operated with the stan- dard knob. The indexing plungers are designed such that the plunger set in the end position (pressure 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. The screw drivers GN 613.1 (available as accessory) shorten the assem- bly time and make it easier to hold the mechanism in place while fixing the lock nut. The screw driver is inserted in the side between the knob and guide, where it engages the slot in the guide. see also... • List of Indexing Plunger Types → Page 884 ff.
