Frequently asked question (FAQ)

Question: What role does a ball plunger play?
Answer: It specifies the stroke of the front ball and can be used for temporary positioning and indexing of workpieces.
Question: What role does a spring plunger play?
Answer: With pin-shaped front section, it can be used to eject workpieces or stoppers.
Question: What is the meaning of load min and max?
Answer: The min. load represents the initial load, and the max. load represents the load at the maximum press-in limit of ball head.
Question: What is the anti-loosening treatment of a ball plunger?
Answer: It refers to fixation using anaerobic adhesives filled in microcapsules. A ball plunger will fail once it becomes loosened, so it is necessary to use anaerobic adhesives for threads. An ideal anti-loosening effect will be achieved when placed at a temperature above 25℃ for 72 hours.
Question: Can the knob plunger withstand radial force?
Answer: No, it can only withstand axial force.
