Specification
Information

Body: Steel, nitrided, blackened finish
Knob: Technopolymer plastic (Polyamide PA), matte black
Lock nut: Steel, blackened, ISO 8675

The indexing pin in the GN 514 locking plunger is moved by means of a spring-operated cardioid curve. By simply pressing the operating button, this cardioid mechanism causes the indexing pin to extend and retract (push-push locking mechanism). This function is similar to that used in a ball point pen.
Please note that the indexing pin cannot absorb any axial foces and that it retracts virtually by spring action; the indexing pin must therefore remain free and easy to move.
Installation can also be made with spacer bushings instead of the lock nut.
Heat resistance of technopolymer plastic: 195° F (90° C).
Spacer bushing GN 609.
