This mechanism means that the plunger pin is both extended and re- tracted alone by pressing the operating button (PUSH-PUSH locking mechanism). Please note that the plunger pin cannot absorb any axial forces and that it retracts virtually by spring action; the plunger pin must therefore remain free and easy to move. see also... • List of Indexing Plunger Types → Page 884 ff. • Distance Bushings GN 609.5 (to Limit the Thread Length) → Page 952 • Flat Hexagonal Nuts GN 909 / GN 909.5 → Page 953 • Positioning Bushings GN 412.2 / GN 412.4 → Page 954 Information GN 514 Locking Plungers with PUSH-PUSH Locking Mechanism 1 d 1 2 Type How to order 1 2 GN514-8-A 2 Type A without lock nut AK with lock nut • Steel - - Nitrided - - Blackened • Knob Plastic (Polyamide PA) Black, matte finish • Load Rating Information → Page 2132 • ISO Fundamental Tolerances → Page 2151 • Plastic Characteristics → Page 2158 • RoHS Specification Spring load in N ≈
