The GN608 series is a precision component for mechanical positioning and indexing using a positioning mechanism indexing pin. It adopts a spring-loaded plunger that extends and retracts, automatically locking into a preset hole or groove during equipment movement to achieve precise indexing or locking.

Features of GN608 Indexing Plunger
GN608 Index Spring Plunger Title:
Mini Indexing Plunger GN608 stainless indexing plunger for Gym
Indexing Spring Plunger Introduction:
The GN608 series is a precision component used for mechanical positioning and indexing, which achieves repetitive position locking and buffering through a spring loading mechanism. It is widely used in high-precision scenarios of automation equipment;
Flanged Indexing Plunger Model Number:
Core Function:
Positioning mechanism: using spring-loaded plunger expansion and contraction to achieve precise indexing or locking;
Reset function: Optional versions with or without a reset position (With Rest Position), the former keeps the bolt head retracted in non working state;
Material properties:
Body with flange: Zinc-plated die-cast zinc alloy with two holes for assembly with countersunk head screws.
Plunger: Stainless steel AISI 303
Nickel plated or Black-oxide steel with hardened end.
Knob Material:
Plastic (Polyamide PA)
Color:Black, Finish:Matte Finish
Knob Feature:Not removable
GN608 Indexing Plunger with Lock Out:
Stroke: 6 mm (or as per your request), allowing the bolt to move between locked positions.
Initial Load: Approximately 8.5-15.5 N, providing stable locking force.
From Head to Flange Length:31mm,36mm or As your Request.

Installation dimensions:
Flange Width: 40mm, 46mm or as per your request
Plunger Pin Dia.:6mm,8mm or As your Request
Flange Center Distance:30mm,34mm.
Application:
CNC lathes, machining centers, automated guidance, robotic arms, conveyor systems, heavy equipment, etc.

Notes:
Stainless steel versions (such as GN608.6) are preferred for humid environments.
Recommended for high-frequency vibration scenarios with reset position design;

Pre-Installation Check:
Clean the base: remove oil stains and debris from the installation holes;
Component inspection: Confirm that the plunger model matches the installation hole.
Installation steps
Align the flange
Align the plunger flange surface with the base plane, ensuring that the bolt head is facing the positioning direction (the "static position" needs to be aligned with the mechanical motion trajectory).
Carry out appropriate tightening and verticality correction work.
