What role does a ball plunger play?

It specifies the stroke of the front ball and can be used for temporary positioning and indexing of workpieces.

What is the anti-loosening treatment of a ball plunger?

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.

What is the meaning of max load and min load?

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.

What is the difference between a ball plunger and a spring plunger?

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.
