Frequently asked question (FAQ)

Question: Can the indexing plunger withstand radial force?
Answer: The indexing plunger is not recommended to bear radial cutting force, as it is prone to product damage and fracture, and generally it can only bear axial force.
Question: What role does a indexing plunger play?
Answer: It is a mechanical element part that can easily and quickly locate and fix the workpiece by operating the knob or the handle to pull out or insert the pin.
Early indexing plungers were mainly used for parts used in the angular positioning of indexing devices.
In recent years, indexing plunger has been more widely used, and become an indispensable mechanical element part of equipment and devices.
Question: What is the difference between reset type and self-locking type indexing plungers?
Answer: The self-locking type can lock the front end by turning 90° after pulling out the knob, while keeping the pulled state and turning 90° to release the lock.
