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 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: What is the meaning of max load and min load?
Answer: It refers to the load of the spring in the product. The min load represents the initial load value, and the max load represents the load value at the maximum press-in limit.
Question: What is the difference between a ball plunger and a spring plunger?
Answer: A ball plunger is headed with a steel ball and its stroke is the displacement of the ball. A spring plunger has a pin-shaped front section and the displacement stroke of the pin is used for such purposes as temporary positioning and indexing of workpieces.
